Troopea

Troopeas are Koopas with sprouts on their heads; Troopeas are only found in the Beanbean Kingdom. They 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.

Later, in Gwarhar Lagoon, a stronger version of Troopea called the Elite Troopea appear. Elite Troopeas can heal defeated monsters, bringing them back with half HP.

There are winged versions of Troopeas, called Paratroopeas. The same goes for Elite Troopeas.

Trivia

 * Troopea's name is a portmanteau of "Troopa" and "pea", the latter of which is a vegetable not unlike the bean.
 * Troopeas look like the Pokémon Turtwig.
