A new sport is in town, called Bully Fighting, where male bullies use adults as the bulls after hyping them up on coffee. Numbuh 4 participates in the sport, but his teammates disapprove, because they only fight evil adults. After a twist of events, will Wally see the error of his ways?
Plot
Wally becomes a Matador in the local bully fighting arena, where, in a parody of bull fighting, he taunts and defeats men who attack like bulls. When he gets back however, the team asks where he's been, and Numbuh 3 exclaims in horror that he went bully-fighting again.
The other operatives then reveal that they only fight evil adults, and that the ones used for the bully fighting are treated inhumanely and drugged up on coffee to make them act the way they do.
Numbuh 4 ignores them, and sneaks out to go bully fighting again while the others try to defeat Soccer Mom.
Numbuh 4 can't believe he must use his own father as a bull.
However, he discovers, to his horror, that the bully he has to fight is his dad.
When his dad comes to his senses (thanks to a smack from Numbah 4), and tearfully relates how he and the other men were lured to the arena after being told that a conference detailing how to be better fathers was occurring at the arena, but they were then captured and force fed coffee, and forced to fight.
Wally turns against the kids running the bully-fighting, and frees the fathers who were being held prisoner. The fathers are later seen trampling Soccer Mom.
Post-Credits Scene: Numbuh 4 playing with his dad and getting chased by a throng of bullies.
