Koops is a timid Koopa that lives in Petalburg. When Mario arrives in Petalburg, Koops begs for him to let him come and fight the dragon, Hooktail. Koops's father, Koopley, had been defeated by Hooktail sometime before Mario's arrival, and Koops wanted to assist in finally defeating it. After Hooktail's defeat, Koopley was found to be alive in Hooktail's belly. Koops's first attacks are the same as Kooper's but his others are Shell Shield, which defends Mario with a large shell for several turns, and Shell Slam, which attacks all ground enemies, piercing through their defense.
