Professor

The Professor (referred to as "Per'fessor" by Captain Plunder) is an anthropomorphic purple walrus (vaguely resembling an elserly Joe Sushi). He is an academic from Metropolis University, who somehow fell in with Captain Plunder and his Sky Pirates. He joined Plunder on an expedition to the Sandopolis Zone on the Floating Island, to find the Lost Pyramid of Sandopolis. It was the Professor who activated the secret controls (using Plunder's old parchment) to lift the Lost Pyramid up from beneath the sand. The Professor accompanied Plunder and Filch into the pyramid, and attempted to steal a sack full of the lost treasure. However, like the others, the Professor was scared of the pyramid's ghosts and dropped his sack while escaping. He presumably rejoined Plunder's crew.
