Justin's House

S6 • E10 Aug 14, 2023 22m
Robert returns from his holiday to find a very messy house because Justin and Little Monster haven’t done any tidying whilst he’s been away. To stop it from happening again, Robert makes a big machine that keeps an eye on the house and sounds an alarm when someone is about to be messy. But, it's very loud and causes everyone to make a mess!
