30/30, and question 31 is collecting a key after a bowser fight. I gave myself a point for question 18, even though I didn't say the same thing as you... that same piece of music also plays whenever a message box appears in peach's castle (such as the messages that appear when you've got enough stars to open the power doors)
★ 30 (and the bonus) We've all had quite a lot of experience with this game. Shoutout to "Ultimate Koopa (In-Game Version) - Super Mario 64" by SiIvaGunner
Even if Super Mario 64 isn't my favorite game or anything, I'm confident and excited to try this one out! I've played it dozens of times throughout the years (even though I've never actually beaten it lol), so I think I'll do at least OK on this one lol. Anyway, here are my answers: 01 - Sliding/Athletic theme ✅ 02 - Bowser fight ✅ 03 - Dire Dire Docks (water levels theme) ✅ 04 - Big Boo's Haunted Mansion ✅ 05 - Bob-omb Battlefield ✅ 06 - File Select theme ✅ 07 - Select mission theme ✅ 08 - Bowser stages theme ✅ 09 - Boss fight theme ✅ 10 - Cool Cool Mountain/Ice stages theme ✅ 11 - Last Bowser fight theme ✅ 12 - Speaking to Toad ✅ 13 - This sounds like a credits theme, but as I said, I've never beaten it, so I'm not really sure lol ✅(makes sense!) 14 - Getting a star ✅ 15 - Lethal Lava Land/Shifting Sand Land ✅ 16 - Sleeping Piranha Plant theme ✅ 17 - Using the metal cap ✅ 18 - First part of the intro cutscene, when Peach's letter is on screen ✅ 19 - Trying to climb the infinite staircase to Bowser's last stage ✅ 20 - Puzzle solved ✅ 21 - Second half of the intro cutscene, after Peach's letter ✅ 22 - Pause screen ✅ 23 - Boo's merry go-round ✅ 24 - Star showing up ✅ 25 - Hazy Mazy Cave ✅ 26 - Don't know this one ❌ (oof, had totally forgotten this one lol) 27 - Theme after beating Bowser for the last time ✅ 28 - Leaving painting after beating a mission ??? (I'm not sure if I should get a point on this one, I didn't know there was a different theme for the 1st mission completed lol) 29 - Winged/Invisible cap/Riding shell theme ✅(I only remembered the 3rd one because you guys specifically said this played in 3 occasions lol) 30 - Little theme that plays when starting a race against Koopa the Quick ✅ Bonus - Getting the keys from Bowser ✅ Wow, I did way better than I expected! The Lakitu one totally caught me off-guard, so I got either 29 or 28 depending on question 28 lol, but either way, way better than I was expecting! I love these music guessing quizzes! I would love one of these on Banjo-Kazooie, it's the one I'd be the most confident in getting all answers correctly lol
We probably just did a bad job wording the answer for #28. Based on your description it sounds like you knew exactly when the song plays! Glad you're liking the quizzes! We'll definitely be making a Banjo-Kazooie one at some point in the not-too-distant future. Banjo's soundtrack holds a special place in our hearts, so we can't pass it up 😊
30/31, final one is the jingle that plays when you complete the first two Bowsers. I mistook #18 as the song that plays if you get a certain amount of stars to open a door, which technically isn’t wrong I guess.
