I found another one just a second after my first post.
If you have Yoshi get hit at the same time you try to eat those volcano, fire spitting looking plant. If you timed it correctly, then Yoshi should have let go of it a few inches of where it was originally. The plant will try to spit fire ut it can't. But the next time it will.
The ingredients for this one are Caped Mario, a P-switch, pipe, and a level area for you to stand on. Fool around withe the P-Switch by grabbing it and spinning around with it. If you keep spinning around like crazy and kick it when you are right beside it, it will be kicked inside the pipe and go back and forth very erratically.
Uuuuuuh... next one. Well, I don't really know how this one happened but if you are Fiery Mario and you fireball a pirahana (I hope I spelled that right.) plant in an upside-down pipe right as it is going back up into a pipe then the coin should jump into the pipe and just go back and forth kind of slowly in the pipe...... forever.
"Yesterday, when I''m smaller..... I wanna fight that Mario the day before yesterday."
