Gloom Beach is a beach that the Monster High student body enjoy going to. At Gloom Beach, the North Beach is a popular holiday resort, whilst the South Beach is used exclusively as a fearleading camp, which is headed by Scary Murphy. Gloom Beach isn't actually a beach as such, as it is a lakefront rather than a seafront. Gloom Beach also provides underwater camping facilities.
So far the webisodes where the girls mention it are in Scream Building, Fear-A-Mid Power, Gloomsday, Fatal Error, and Screech to the Beach. In Fatal Error, the girls are chosen as the "Wild Card" pick to attend Gloom Beach Fear Camp and in Screech to the Beach they arrive at Gloom Beach to find out they were assigned a gross, broken-down room.
The girls continue to stay at Gloom Beach for the episodes Witch Trials, Don't Cheer the Reaper and Road to Monster Mashionals, the last of which sees them winning the Spirit Staff at the Fear Camp's Fearleading competition. Both the North and South beaches are seen briefly in each episode.
After winning the Gloom Beach tournament, the girls take their time to relax on the beach. The same is true for Ghoulia, who arrives with a large amount of books she intends to gain knowledge from. Cleo is appalled by this, certain that her friend does not know how to have a good time. As such, she and the rest of the girls organize a day of fun for Ghoulia, despite Ghoulia's insistence she already was having fun.
First of, the girls get Ghoulia dressed in appropriate beach attire. Next, the girls go on to build sand castles. Ghoulia starts work on a sturdy, real-life scale castle of sand, but her design stand is knocked over by Heath. Next, Frankie and Cleo take Ghoulia aside for some archery practice. Slo Mo and Don watch as Ghoulia prepares her bow, upon which Cleo takes off Ghoulia's glasses to make her look prettier. As a result, Ghoulia misses the target and accidentally hits Hoodude, whose pain is transmitted to Heath.
Distraught about the depressing experiences, Ghoulia walks off to cry. Cleo and the girls come after her, and Cleo apologizes for insisting that Ghoulia has fun their way instead of her own. Ghoulia accepts the apology and goes back with the others. First, Ghoulia completes her sand castle, which all of the girls find fun. Next, she tries archery again, but this time with her glasses on, and hits the bullseye. As the others are cheering, Cleo admits that Ghoulia's definition of fun is pretty fun.
- Gloom Beach also is the name of the first doll line featuring beach attire.
- Mattel held and holds a poll on the Monster High facebook account that asks fans to vote what their ideal Spring Break vacation would be. The options are the Great Scarrier Reef, Monster Horn Mountains and Gloom Beach. Needless to say, as the only location mentioned anywhere outside the poll, Gloom Beach is the favored choice by far.
