Prongo is an enemy that debuted in Super Mario 3D Land.
This enemy is a small green enemy with a blue, square bucket-like helmet on its head, adorned with spikes. These enemies attempt to attack Mario by jumping on them. When they jump, they become lodged in the ground, and reveal their soft underside where Mario can jump upon, defeating them. The Prongo will disloge itself from the ground in a short amount of time. Mario can also use his tail to defeat them.
