A giant and scary monster shows up to stay at Shake, Rattle, and Roll's haunted inn. When he scares away the other guests and creeps out the ghostly trio they attempt to scare him away. When their attempt fails they are more than happy to trick Sidney into sucking up the monster with his ghost vaccum. This brings back their ghostly guests and all is well.

In this episode Sidney shows up and freaks out the ghostly trio. In attempt to capture all the ghosts Sidney recruits a robot to help. During most of the show the trio has to run around to get their guests out and away from the robot and Sidney. In the end the robot leads Sidney to believe all the ghosts are gone so the inn's real owner comes back. However right before paying Sidney the owner gets a call from somebody who was going to pay $2000 just to stay at a ghost-infested inn so he chases Sidney out of the inn and into one of those moon sunset things.
