It's Spring Break and the student body of Monster High kicks off with a carnival to celebrate. Frankie, Clawdeen and Draculaura marvel of their plans to spend the break with Lagoona, who invited them all to the Great Scarrier Reef. Lagoona also surprises her boyfriend, Gil, to invite him along in order to finally meet Lagoona's parents. Much to Gil's horror. Operetta, Spectra, Clawd, and Deuce all received invites as well, but they politely declined with plan of their own. This leaves Lagoona herself, Cleo, Clawdeen, Draculaura, Frankie, Abbey, and Ghoulia for the trip together.
