A woolly mammoth monster introduced in Monster Farm Online. It has a large set of tusks as well as a pair of ram-like horns. It seems to be used as a pack animal in the snowy mountain regions of the Monster Rancher world and they also seem to replace cows in some areas. There is a large non-playable elephant/turtle monster in Monster Rancher 4 named Garp who could be an early type of Mamuu.
NOTE: Technically, no sub-Breeds can be created through combining in Monster Farm Online or Monster Farm Lagoon, but based on colors and attributes, educated guesses were presented on some of the sub-species for clarity
