Stuffwell

Stuffwell is a living suitcase created by Proffesor E.Gadd to aid 'Super' Mario on his adventures. He is essentially a suitcase who can store many things, but he also has the remarkable ability to backflip into Mario's pocket and stay there for ages, even through tedious bossfights.

Stuffwell has a load of weird gadgets as well, like a cross-dimensional communicator, a time machine and a reinforced storage chamber. He can speak perfectly normally but he uses strange words like 'nincompooter' to suppliment words he doesn't know.
