Biffidus
The Biffidus is a member of a tribe-like group of Biffidus, who help the parasite worm Durmite. They are rounded in shape and carry spears, which they use to attack. During the events of Mario & Luigi: Bowser's Inside Story, Bowser ate a huge carrot, which unknown to him at the time, contained Durmite. The Biffidus helped Durmite in battle, by trying to jab Mario or Luigi with their spears. However, after taking much damage, Durmite would eat the Biffidus, then regurgitate them at Mario or Luigi, which they must jump over the flying Biffidus. It is unknown why the Biffidus assisted Durmite, even though she ate them repeatedly. However, the Biffidus were no match for Mario and Luigi, and were ultimately defeated, along with their master, Durmite.
