The Rappasawrus is a custom designed robot created by the Beat Box Bears from a do it yourself robot kit. The Rappasawrus was built to be a professor of global studies specializing on how to teach kids to go green for the planet, on how to recycle everyday items while having fun through songs he's made up himself.

Often he likes to address himself as "Professor Alexander Rappasawrus" and speaks with multiple accents he picks up from watching T.V He also has a 1,000,000 gigabyte hardrive with the G.P.S that allows him to swim, fly and skateboard just like the pros. The Rappasawrus also has a solar powered dog named Doggy who will do anything for a "Rappa Snack". Although he doesnt have legs and just rolls around on wheels he always manages to help the Rappasawrus on his daily adventures.
