The Mabu are a species of mammal-like creatures in Skylands. They largely populate the world and have many villages around the islands. Most of them have peaceful lives and are not used to the destruction Kaos is creating. However in many levels with where the Skylanders require support, the Mabu Defense Force is called to help them against Trolls and obstacles.
It is possible for the Mabu to have races as they are all different anatomy-wise. For example, Cali and Flynn are much taller than most and the former has stripes, and Hugo has long brown fur.
