Glumps are the naughty, fiendish helpers to the sinister Dr. Strangeglove (Lavender Troggs) who love to eat and steal cupcakes. There is a game called Moshling Boshling, much like Angry Birds on Main Street that everyone can earn Rox from, a type of money, where Glumps are trying to steal cupcakes from a Monster Couple. Dr. Strangeglove was the criminal mastermind who created these Glumps using a powerful machine. Glumps are really Moshlings that have been turned into glumps by that same machine. Glumps can also be very cheeky, trying to stop Super Moshis from saving moshlings or Monstro City.
