Tuskelak

The Colloselak and Gigaphant constantly fought for food. The Collesellak eventually evolved into the very aggressive Tuskelak. This aggression was so severe, that it will kill other herbivores on sight, thus driving the Planda and Forest Gigaphant to extinction. Its teeth and knee spikes have grown into long tusks, with which it will impale any competition, including other Tuskelaks. Most predators stay away from fully grown Tuskelaks, but will hunt babies. Like its ancestor, it just eats and chews cud as it crashes through the forest. It will eat any plant it can and is always hungry. Its back hump can store food during lean times. They have also long since lost their color-changing abilities, since nothing messes with them.
