Albert "Al" and Moose "Moo" Sleech are two nerdy twin brothers, who are both 10 year old geniuses. They made their first appearance in the episode Doug and the Weird Kids, in which Doug was paired with the two to get to know them for a school report. Their father is a baker and they have tried to keep Doug from seeing him due to their embarrassment of this. Since then, Doug has gone to them for technical help when needed, and they have made many appearances.

Doug once accuses Al and Moo of destroying his prized bike.

Not much is known about the twins' background, although it is confirmed that the two moved to Bluffington later than Doug.


Al and Moo seem rather closed-off to social interaction
