Note: To wavebounce, you must be inputting a special move (B move) in one direction, then smash the analog in another direction immediately after. The character's movement makes some funky combinations.
Just to list an example of a funky combo (assume Yoshi is facing to the right):
SH/FH Backwards > UpB to the Left > Smash the analog stick to the right > Yoshi changes direction to the right, throws the egg to the left.
Now if you do the same motion, but jump forwards instead, he'll move backwards while egging to the right.
