A peculiar property of Jump Physics and the Goomba Stomp, where stomping on an enemy - any enemy - lets you bounce upwards to greater height than your normal jump permits. Enemies in these games must have rubber bones or something. Typically, to perform this technique, the player must be holding the Jump button when the character lands on the Mook. Though in some games, the player may have to do a timely button press as he lands on it or almost immediately after for this to work. Sometimes, performing a second Goomba Stomp from one of these jumps gets you even more height.
