oh this reminds me, i found a glitch in dkc2 the other day. i'm sure it's well-known in some even nerdier community than the smash bros one, but i've never heard of it. it probably works either way but is likely easier like this: have diddy throw dixie, and then jump just before you recatch her, and you go about twice as high as you should. i found this in a bonus level on the Slime Climb level in "world" 3...there are a bunch of bugs off to the right, and platforms to keep jumping up on the left. if i hit a bug with dixie and jump with diddy at the right time, i jump up two platforms.
other things...if you're doing a throwing animation, you pass through ropes (like at the beginning of bramble scramble)...and i think if you get shot out of a barrel in air, you don't slow down when you hit water, but keep going as if it were more air. either that or there's some kind of similar glitch near the end of slime climb...there's a barrel at the end that shoots you onto the finish flag thingy, but if you, uh, DI left instead you start falling through the water.
