"Booger is Goober’s little brother. Booger is good at math, but he’s a little absent-minded (just like his brother). He’s a sweet kid with a bit of a mischievous streak. He’s a friend of the ‘Kinz, but not really in the inner-circle."
Booger can be found in the following books:
- The Smarty Pants Storybook
