Biffidus

The Bfizu person is a member of a tribe-like group of Bfizu people, who help the parisite worm Imonu. They are rounded in shape and carry spears, which they use to attack. During the events of "Mario and Luigi RPG 3!!!", Bowser ate a huge carrot, which unknown at the time, contained Imonu. The Bfizu person helped Imonu in battle, by trying to jab Mario or Luigi with their spears. However, after taking much damage, Imonu would eat the Bfizu person, then regurgitate them at Mario or Luigi, which they must jump other. It is unknown why the Bfizu person assisted Imonu, even though she ate them repeatedly. However, the Bfizu people were no match for Mario and Luigi, and were ultimately defeated, along with their master, Imonu.
