Yoshis
From a really old puzzle hack that I never finished and just found again. This level was going to be scrapped anyway so I may as well post it here since I thought it was kinda cool.
Actually this wasn't even the original solution, it's just been so long that I can't actually remember what it was, haha. It is mostly identical to what I recall though. The goal was that it was supposed to be doable without tools, even with the whole "you can see the dang Yoshis" issue.
