Mr. Spoon is a curator found in the back of the Fourside Dinosaur Museum. He tells Ness there is something shiny behind the door he guards, but will only let him and his friends through if they get him a signature from the popular singer Venus. The group has her sign a banana peel when they go see her backstage and then they take it to Mr. Spoon. He opens the trapdoor so that the group can pass through the Fourside Sewers and find the fifth "Your Sanctuary" location, Magnet Hill.
During Venus's performance, Mr. Spoon can be seen trying to get onto the stage with her but is stopped by security and is escorted off of the premesis.
