Growing up in the quiet town of Norco California proved to be too boring for an ambitious horse like Mini. When Rob and Big offered to adopt him, Mini left his farm for the glitz and glamour of Hollywood.
After a rough first night in Rob and Big's living room, the boys built him his own horse pasture and a replica of Three Layers of Heaven. He also gets to cruise around town in his own fantasy-scape trailer. Mini has trained with fabled Mini Horse trainer Flame, who has taught him such valuable skills as wearing a bridle and not biting people on their butts. Mini enjoys pulling Rob on his skateboard, kicking it with Meaty and Big, and leaving lots of meadow muffins for Drama to clean up.
