Back in the 1900s, deep in Alaska, a group of miners were blasting dirt, ice and what not searching for precious metals. Instead they discovered an unknown species of dwarf T-Rex. The miners' dynamite stirred something in this cantankerous critter and he developed a taste for it. Soon their entire stash had been grabbed up. When he couldn't have any he'd get mad and bellow so loud that they decided to name him RAAAR!
