Desperate for a solution, Mac begs the gang's resident inventor, Bloo, to create a device that will exterminate the fleas once and for all. But after several attempts, Bloo's inventions fail to do the trick.

There, they discover an entire civilization of tiny flea creatures, complete with their own king and queen. The gang comes face-to-face with the flea monarchs, who are none too pleased by the Foster's residents' attempts to get rid of their subjects.

But when the gang explains the trouble the fleas have caused in the house, the flea royalty agrees to help them solve the problem. They devise a plan to send the fleas out of the house and into the yard, where they can live freely without harming anyone.

With the fleas successfully relocated, the Foster's residents breathe a sigh of relief. Madame Foster returns from vacation to find the house in pristine condition - and the gang is hailed as heroes for their ingenuity and bravery.
