Monster Buster Club

A popular new cheerleader invites everyone at school to her big party, except for the MBC kids. Cathy snags an invitation but is trapped with everyone else when the cheerleader turns into an alien intent on taking the entire school (students and building) hostage.

The MBC protects Cathy's mind-reading, alien cousin Elton from the Pincher Bots that want to capture him. In the process, Elton reads Danny's mind and accidentally reveals one of his most embarrassing secrets to the entire school.

The kids must take action when Mark mistakes Mr. Smith's universal communication device for his cellphone, and almost starts an intergalactic war with his rude remarks to the alien callers. Cathy, meanwhile, has discovered the Earth concept of phone gossip.

Sam tries to simultaneously run a school bake sale, and help Cathy babysit for a very hungry toddler, who turns out to be a "dangerous" eater alien. Danny and Chris, meanwhile, must compete against Mark's extravagant efforts to ruin their bake sale.

Cathy gets detention only to find that the teacher in charge is an evil alien! Chris, Sam, and Danny attempt to cause "trouble" and get detention as well to assist Cathy in defeating the Sticky teacher.

Danny agrees to watch his crush Wendy's dog, but ends up putting the pooch in a kennel. When he gets the dog back, it's a robot! Meanwhile, Cathy is trying to come up with an "acceptable" project for an Earth science fair.
