From the Super Mario Wiki
Magifoofas are Fawfulized Magikoopa enemies who appear in Bowser's Castle during the events of the game Mario & Luigi: Bowser's Inside Story. Bowser can defeat this enemy by simply touching it in the overworld, which means that only the bros. can fight them.
In battle, they can use their magic to summon shapes above the Mario Bros., which will then solidify. The shapes formed are a triangle, a square, and a circle. The Bros. will have to jump over the triangle and square in order to prevent being damaged; however, the circle will simply bounce over Mario and Luigi's heads. If timed well, the triangle or square can be crushed by a jump counter-attack. Occasionally, the spell may turn into a Bean similar to the ones the Crawfuls eat, which is indicated by black smoke coming out of the Magifoofa's wand. The bros. will simply need to jump over this attack. It can also heal itself and its allies when in battle.
