Six different types of these large mammoth reaverbots can be found throughout Terra. The first two, identical in appearance, both appear on Forbidden Island. Type 1 hides beneath mounds of snow, while an endless amount of type 2 charges down narrow pathways.

The 3rd type can be found in the Kito Caverns on Calbania Island, while types 4-6 are all within the Calinca Ruins. Type 5 must be lured into pits in order to stop and seal them away.

The same attack pattern applies to all of the different Mammoo. Upon sighting their target they will let out a roar and rush forth in an attempt to ram it.
