Infinite Jump Farm
How to perform this glitch:
First go to 'Condarts away' and pick a not easy mode character (reason: they always break the block) . Then, go to the area with the big drop and take a shell down there. Once you've made it down there without killing the shell, kick it to the left set of blocks so it hits the bottom ones. Then kill the left condart and take so much damage, until you're small and can't break blocks anymore. Then go under the block (if it's too hard crouch and you'll not jump as high) and then you'll jump quickly. If you also want the jump sound, press the jump or spin-jump button a few times until you hear it.
