The gang is getting ready for a visit from the ambasador of the molemen. Les had only one thing to do, take out the trash which he put off to play video games. Now the guest is here and there's a ton of trash in the yard. Dad has to rush off to save Mom from Yetis. The gang finds out that molemen like eating trash and start by serving up what they have in the yard. A problem right off is that the molemen become extreamly fat on the trash. They gather trash from all over and dump it down a hole for the molemen who want more and more trash. When they don't get enough trash the now large molemen begin popping up all over town only to get stuck in their own holes due to their size. The gang starts the music to get the molemen active and thining down and able to pop back into their holes just as dad returns home.
