It's Not Fair - S1.E10

The Safety Inspector arrives to make sure the Hotel measures up to Zombie standards. He runs a “fresh air drill” (clean air is bad!), checks Dame Fedora’s shriek for effectiveness and makes sure the dining room chairs aren’t too straight. Meanwhile, Fungus, Maggot and Sam are the laughing stock of the school for their science project. Wanting to help, the kind-hearted Francis steals the other kids’ experiments so that Maggot/Sam and Fungus will win. It doesn’t take long for the police to track down the culprit and cause more mayhem at the hotel.
