Spud

Spud is a carny and the son of Cooder.

History
When the Simpsons went to a carnival, Cooder and Spud were working in the ring toss game. Through a series of mischances, Homer and Bart ended up working in the booth and lost it when Homer bungled Chief Wiggum's attempt to accept a bribe, this ruining Cooder and Spud's livelihood. The carnies then ended up staying at the Simpson home and caused a lot of trouble, culminating in tricking the family out of the house and forcing them to live in Bart's tree house. The Simpsons got the house back by betting the deed in a ring toss game, then taking it back by cheating. The Simpsons then moved back into their house and Spud and Cooder went back to being carnies.

When the Simpsons stopped at the State Fair, Cooder and Spud were seen in the carnival, working the ring toss booth.

Non-canon
In The Simpsons: Hit & Run, Spud appears as a civilian on the streets in Level 1 and Level 5.
