- "Why didn't you say so?"
- — Mr. Scatterbrain's catchprase
4 February 2008
He is voiced by Joey D'Auria in both the US/UK/Australian dubs.
Mr. Scatterbrain was made for The Mr. Men Show as a counterpart for Little Miss Scatterbrain from the books as executive producer Eryk Casemiro stated that the female characters in the series should remain mostly positive.  He is a pear-shaped magenta Mr. Men character with a blue bowler hat, a pink nose, a unibrow, and a wide collection of random items. Unlike the other characters, his tongue is hot pink. He also has a lot of animal friends, ranging from penguins to iguanas. His catchphrases: "Why didn't you say so?" (evident that he has short term memory loss) and "Where is my head?" He resides in Dillydale.
