The Sweathogs try to form their own gang in response to a scare from another gang. Gabe, Arnold, and Mr. Woodman act tough enough to scare both gangs out of any violent activity.

Sparked by the fact that Vinnie neglected to do Freddie's homework, the Sweathogs spend the better part of class fighting with one another.

The Sweathogs go on a field trip to a museum and meet its mysterious, superstitious curator. In the process, they all get locked in a tomb of a mummy which supposedly holds a curse.
