Monster High has a leaky roof problem and the only monster that can fix it is a gargoyle. So it’s up to the Ghoul Squad to travel to Paris where they try to recruit Rochelle to come back with them and save their school. Rochelle agrees to help, but can’t leave until the ghouls help her deal with a troublesome, roof-destroying gargoyle named Rockspierre. And back at Monster High, Clawdeen struggles to come up with a perfect piece for an upcoming art show.
