Mimedon inflate the rubbery material around their faces to repel attacks before flailing back and forth to swat away foes. The orbs at the end of their ribbons jingle faintly as they bounce around.
The orbs on Mimedon's body jingle like bells when its sturdy skull is struck. Groups of Mimedon headbutt each other to strengthen their skulls, creating a cacophony of bell-ringing.
