Sir Arthur is a character from Danger At Ocean Deep. He is the president of Allpets, the company that produces dog food containing the OD60 sea fungus.
A Visit from Lady PenelopeEdit
Once Brains reveals that the high-density fuel is Liquid Alsterene and that OD-60 is a sea fungus used in the production of dog food, Jeff realizes that this reaction must be the cause of the destruction of Ocean Pioneer I. Lady Penelope visits the dog food manufacturers Allpets and learns that they have dumped large deposits of active OD-60 into the Mediterranean in the hope that it will grow there.
- Sir Arthur makes a cameo in The Cham-Cham, as a guest at the Paradise Peaks Hotel.
