From the Super Mario Wiki
Troopeas are Koopas with sprouts on their heads in Mario & Luigi: Superstar Saga and are only found in the Beanbean Kingdom. Their name is a portmanteau of "Troopa" and "pea", the latter of which is a legume, not unlike the bean. Troopeas have dark blue shells and are found mainly in SE Beanbean, near Woohoo Hooniversity. Troopeas are rather basic enemies, although they can create small water droplets that restore HP in their allies. If Mario or Luigi manages to jump on a Troopea's shell while countering his ramming attack, the shell will be shot toward the other enemies on the battlefield and will damage them.
Later, in Gwarhar Lagoon, a stronger version of the Troopea called the Elite Troopea appears. Elite Troopeas can resurrect defeated monsters, bringing them back with half HP.
There are winged versions of Troopeas, called Paratroopeas. The same goes for Elite Troopeas.
