Jump Helmet is a Special Attack that appears in Mario & Luigi: Bowser's Inside Story and Mario & Luigi: Bowser's Inside Story + Bowser Jr.'s Journey. It costs six SP to use this attack in the original and ten (twelve on Easy) BP to use the attack in the remake, though it is increased to ten in the remake. In order to use it, the player must collect all 10 Flab Zone Attack Pieces.
When using this item, Luigi puts an orange helmet (somewhat resembling a Buzzy Beetle's shell) with a trampoline on his head. Mario jumps on the springboard, and the player must control Luigi with to allow Mario to land on the trampoline each time he comes back down. If the player presses at this moment, it will let Mario fly higher. After the brothers get close enough to the enemies, Mario lands on the selected baddie, and pressing will end the attack successfully with a ton of damage being dealt to an enemy, although if Mario misses the trampoline, he will fall to the ground and the attack will end without dealing any damage. The attack will be stronger depending on how many times Mario successfully landed on trampoline (with the command), as well as how well Luigi lined up with his brother each time. The best result has Mario jumping higher than the screen for the final jump, while somersaulting for every jump.
The Juuuuuump Mode in the Challenge Node is solely focused on the Jump Helmet. Making Mario jump to the right of the helmet makes him jump farther and making him jump to the left makes him jump higher.
