With Emily in hospital having her tonsils out and a history project due, Hank decides that the best course of action is to take Emily's pet lizard into school.

Mr Rock is holding a sponsored school sleepover and it's the best thing ever... or at least it would be if Hank didn't also have to find time to make up for years of lousy Mother's Days by making his mum the perfect present. Can Hank and friends use the sleepover as cover for an emergency session of craft and design? Can Emily get away with bringing her beloved lizard Katherine to school? And will Stan's plans to make Rosa the ideal Mother's Day meal turn out quite as well as he hopes?
