Troopea

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 Troopea called the Elite Troopea appear. 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.

Trivia

 * Troopeas bear a resemblance to the Pokémon Turtwig.
 * When Mario or Luigi jump to counterattack on these creatures, the result is much like the Green Shell item from Mario & Luigi: Partners in Time and Mario & Luigi: Bowser's Inside Story.
 * Oddly enough, the sprout on the Troopea resembles the Floro Sprout from Super Paper Mario.
