In Mario & Luigi: Sibling Rivalry, they are very powerful Bros. Items that require the availability of all two Bros. in order to be used. Each Bro. jumps onto the trampoline, then bounces high up, farther than even the top screen. Then the Bros. come down in random order and stomp on the foe, and if timed correctly, jump back onto the trampoline for a second (third, fourth etc.) jump. If the timing is missed, he will knock the trampoline away, ending the assault after the other one have fallen.
