- "This plucky duck's science degree must have been written in crayon. In fact, some suspect he trained his Doodle to sit it for him. But what he lacks in smarts, he makes up for in other areas. In fact, he makes everything up! Except the Propeller Packs.. those were confidential."

Doctor Dimm is an NPC duck Toon who is a member of the S.I.L.L.I. (Scientists Interested in Laugh Levels Increasing) team for Loony Labs. He can be found in Toon Hall inspecting the Silly Meter with the rest of the Scientoons. Toons may speak to him to grab a ToonTask to retrieve the Silly Reader, and learn more about the Silly Meter and its functions.
- His name is a play on the word "dim".
