Professor Pebble

A short round elderly man with fair skin, a big bald head with fluffy white hair on the sides, an enormous white mustache, round brass goggles on his forehead. He wears a slightly singed white lab coat over a green knitted vest and bow tie, brown trousers, slippers, and holds a wrench and a small whirring gadget.

Absent-minded, enthusiastic, polite, unshakably optimistic.

Retired professor and garage inventor

Professor Pebble's toaster sings, his umbrella waters plants, and his alarm clock makes pancakes. None of these were the plan. His neighbors love all of them.
