What's up With: Sonic Mania! 

Sonic 4: "I'm the game everyone wants!" Sonic Advance: "I'm the game everyone wants!" Sonic Mania: "Hold my beer."

The skits with Cardboard Sliver were hilarious. Always a highlight in the WUW series.

Your speech at the beginning moved me, It's relatable as heck for me because I suck at video games despite liking them a lot!

Cardboard silver coughed?... HE'S EVOLVING. RUN PATTER.

Guy: Hey man I learnt something new today Internet: Cool, what is it? Guy: Opinions Internet: What's that? Guy: Something you'll never understand

Pater: Do not listen to the "haturz", hope you had fun with mania, cause im sure as heck I had a lot of fun watching you play, also, this review, 10/10, idk why but Carboard silver's talk on foam made me curious lol "Whats up with: foam" confirmed?

Peter you should know by now The Internet doesn't allow you to have a opinion

Despite the fact that you draw pictures of 14 yr old boys and talk to yourself every video, i still really like your content. It's funny, it's original and it's much better than most of the trending content on RU-vid right now. Keep up the good work and you'll find yourself on the top in no time.

You got the title wrong. It’s What’s up with: Sonic manyaaaa

Poor Peter 😅 I felt like he was unfairly attacked lol

Happy 1 day late Thanksgiving! I know this video took a long time to make, but I'm thankful for your patience ;) No matter where you live, if you celebrate Thanksgiving or not, I'm thankful for your support over the years, and hope you have a great day!

After a stressful day, it's nice to see a new Pater video Thanks for the upload man and for the Sonic Manyaa! let's plays! I enjoyed them a lot and they make me laugh

What's Up whit: Foam!

Cardboard Silver is quite snappy, geez xD although he has good reason to be. You both had great reviews, I thought I would come here to find just a Sonic Mania review but was surprised to also find a review on..foam? xD Again, great work both of you. Also, Happy late Thanksgiving!

You can't stop Cardboard Silver - It's no use!!!

CARDBOARD SLIVER IS BACK! YAS!!!

...you forgot to mention the bosses...

Can't wait for the next Throwback to the classics: Sonic R 2

May this series Rest In Peace.

Yes, my favorite anime character has uploaded a video.

i love your tiny cardboard silver, he’s a joy to see when you put him in videos

I love your videos, Peter! Never stop making videos! You are awesome!

0:14 I still can't believe someone threatened to swallow their own cat because of Peter playing Sonic that made me laugh so hard

I've beaten Sonic Mania 3 times and about to do it a fourth time with sonic alone because I've beaten it with tails alone, sonic and tails and knuckles. Peter, you've done very well with sonic mania and you played it how you wanted to play it and you got through. Good job man, I love your videos, especially these what's up with videos ^^

The internet is a cruel place.

Senpai when we have our date?

I’ve never had such a good time listening to some sharpie on cardboard talk about foam.

Thank you for being such an amazing content creator and person peter your videos are always the best

(Peter Uploads) Me: *My longest Yeah Boi ever*

Sliver should have a what's up with foam episode

I love watching his old videos. What a timeline.

CARDBOARD SILVER IS FINALLY BACK :D

Every time Peter says "Jump Dash" take a shot of wine. See how messed up you'll be in a second

Who's that lanky blond guy interrupting Sliver's foam review with a manya review? Rude.

0:06 wipe good enough?! Confusedascrap.jpeg

7:49 OMG IM IN HIS VIDEO! :D (top left) XD

Been waiting for a new "whats up with" video forever thanks Peter

make a video about cardboard silver expressing his opinions

💜

Did you know that.. Sonic mania is called.. *Sonic mania!?*

DUDE I MISS THIS SERIES!

What’s up with Peter Knetter’s upload schedule? Love you dad.

The Luma theme still makes me tear after so many years :' )

Yaaaas Cardboard Sliver is back.

Don't worry peter. I've been watching you for 5 months and I watch you almost everyday, I enjoy myself watching your videos and I don't care how bad you do. I enjoyed myself and you make me laugh my ass off. Even if you're bad at Sonic mania, I still love your content and you make me laugh and happy. Just keep what you're doing and screw the haters

Patter, you're not bad at Mania! I'm a lot worse, it took me a week to beat Chemical Plant. XD Keep making more videos and memes m8!

As someone who waited for Sonic Mania since 1994 I absolutely loved it. I wish it had more original levels but apparently that was Sega's fault and they did a good job of remixing the classic stages to make them feel new again. Sonic 3 & Knuckles is one of my favorite games of all time so this game was like a warm hug from beginning to end. I hope the Adventure era fans get their third game someday too.

Finally the what's up with series is back!!! Also are you going to do what's up with sonic forces

Your channel is honestly... Like... OMFG comedic GENIUS I LOVE IT!

It’s okay Petter your awesome don’t trigger from all the comments I’ll be the only nice comment CARDBOARD SILIVER WILL BE MINE

Peter getting told what a drop dash is is like a smash noob getting told to tech

Shun the nonbelievers Yea, shuuuunn Shuuuuuuuuun

"I used to love this channel :( before all he did was upload the game over screen on repeat" "*FIRST*"

Finally, Ive been waiting so long for this I'd almost lost faith in this channel! I suck at sonic mania too, but then I suck at all video games. Sonic Mania was great, I dont give a flying fudge about Sonic Forsucks though.

Poor man just wants to play sonic, leave him alone he's literally vibing.

8:00 And right here, ladies and gentlemen, we have one the greatest arguments between a man and cardboard of *ALL TIME!!!*

One of these days, that Cardboard Silver is gonna get ripped to shreds if he keeps this up! XDD

THE SLIVER DRAWINGS HAVE WORKED! CARDBOARD SILVER IS BACK!

"Those hardcore classic Sonic platformer fans..." *me:* *SammyClassicSonicFan intensifies*

And knuckles

dont worry about what anyone else says just rember that even though the haters are there the people that love you will always be there to support you happy late thanksgiving and i hope that you create lots more of that funny and great content of yours because i know that when ever im feeling down i can come to you to make me feel happy again. thanks for everything peter

Peter I love u man it’s fine your not good at a game u can still enjoy it anyway, your amazing dude

Every time I hear your outro song, I practically scream the lyrics to "I'm a giant sandwich man."

What's up with: Sonic Mania... *& KNUCKLES*

You know, sometimes I wonder if Peter actually thinks Cardboard Silver is alive and the voiceove is just added in post so that Peter would appear a lot less crazy when he realizes that he was just talking to himself when editing the footage. No, seriously, it's impressive how genuine you can make these scripted conversations between you and a cardboard cutout sound. It really feels like Cardboard Silver is alive in these vids, and I love that about them.

I love you patter ;)

And thus the final what’s up with, I miss this series.

Hey Peter, My name is Josh aaaaaand Hi.🙂

I can never get enough of the two tracks Hyper Potions composed for the game! :3 'friends' is exiting while also being (by lack of a better word) somewhat emotional in some places (especially the part that comes after the music originally ended in the intro video), and then 'time trials' is pretty much nothing but exitement and adrenaline. And it's not just the originals I love. Skye Rocket and Chi-chi made lyrical adaptions for time trials and friends respectively, and I know both by heart, that's how much I love them! Hyper Potions really outdid themselves :3

Idk about y'all, but I think Cardboard Silver is onto something. I'd play another Sonic 06. (also foam is great)

I missed cardboard Silver, I always laugh when ever he is there, thanks for making my day, keep up the good work, (don't worry, I suck at the 2d classics, and I play them every day)

Sonic Mania or Sonic Forces?

My friend : Peter talking about literally anything Me: cardboard silver talking about foam

What's up With: Peter Knetter not making more Garry's mod videos

8:07 when i saw those stickers a lot of questions poped in my head

We love you Peter

I feel like cardboard silver should have his own lil show on the channel. Who else agrees?

Ok, Silver, calm down. Actually never mind I prefer you the way you are. Don't let us change you in any way. Also Peter don't change into the perfect gamer... Basically please think long and hard before installing controller cords in your arms. And please don't.

0:44 mate, this is the Sonic fan base, there are NO opinions

“But what if Sonic FORCES them to want it* Wow, best pun of the year goes to cardboard sliver

Do a What's Up With Cardboard Silver where he is the main talker and let him even edit it.

Wait, Sonic mania was 3 years ago? holy chili dogs that's a pretty long time

Your a good player petter there will always be haters though

The story behind the UFO in the special stages: he was a thef and wants to stoled youre emeraaldz. I really love this video! Keep up the good work! Oh and you're not the only one who is not good with the drop dash!

Level Design is an incredibly complex topic to talk about and takes thousands of hours of careful observation and in-depth RU-vid videos to even BEGIN to understand. It's understanding the very fundamentals of what makes video games fun, and some people just can't think that deep. It has to "click" in your mind, and once it clicks you can never go back. Also, when people compare the Classics and the Advances, they're not talking about Advance 1, as it's extremely faithful to the original trilogy and people generally agree that it is comparable in quality to them. Also, the foam thing reminded me of FOAM ADVENTURE, one of the cringiest RU-vid videos ever.

Cardboard Silver is back BABY! He's my favorite character on this channel. Also Peter and him are the best duo on this channel, even if they're both portrayed by Peter.

I used inspect element to make the title say "What's up With: Succ Mania?"

Cardboard Silver or Sliver I got a foam commercial while watching this

The only titles I have beaten is Sonic Rush, and soon I will beat Forces. Soon.

finally another whats up with these are my favorite videos you do also good job with silvers jokes and the foam thing thanks for another amazing video that made me laugh

make whats up with foam

"IF I SEE YOU JUMP INTO A SPiKE ONE MORE TIME...I WILL SWALLOW MY CAT" said by cat guy

FINALLY

I saw this and just got so excited over a new "What's up With" video

Can we have a just silver episode

Rub 2 pieces of memory foam against each other. Most satisfying noise ever.

Do you know how to use the Drop-Dash?

Cardboard silver: Your Mom! Peters mind: wait that has two meanings

Bet u won’t pin this

I like how cardboard silver has more personality and is in the video more, actual interacting.
