There is actually a way to get to Toadette without saving peach or collecting over 100 moons. First off, if you go from sand kingdom to lake kingdom and then from lake kingdom to wooded, there is a trick jump you can do to get to a painting island that brings you to luncheon. Then you can do a trick jump called bruncheon that brings you to the mainland. From there, it's as simple as using cappy in 2 player mode to ground pound with you feet then call him back and at exactly 3 seconds call him back again, which teleports him in front of Mario. Yes, I know you said you didn't want to use 2 player mode, but this can save you 2 toadette moons and make it zero. If you want to know more about bruncheon, watch smallant's star% video. If you want to know more about the 2 player mode cappy trick called a CRC, go to lowest percent's first video.
This is a really good RU-vid video! The video content is good, the concept is good, and overall really fun to watch. I would suggest moving forward to work on the script more and have less self deprecating jokes. I also think speaking with more inflection in your voice would help too. Overall, loved the video!
