From the Super Mario Wiki
Red Coconutter is an enemy in Mario & Luigi: Partners in Time. It is a red, stronger and faster version of the Coconutter. It is encountered in Thwomp Volcano, fighting alongside Thwacks and Tanoombas. Red Coconutters can throw their spears, as well as shoot multiple darts from a blowgun. When a Red Coconutter throws its spear, it indicates who it will attack by it's shining eye. The latter attack has a chance of poisoning its target.
