Slumbo is a Frosticon Mixel.



Thanks to his cold climate, Slumbo is very lethargic and slow in his work. He is also the sleepiest and dreamiest of the Frosticons. He often works slowly with a bit of an attitude. Thanks to a lack of energy, it seems like most actions take everything out of him. It takes extremes to get certain emotions, like shock or anger, out of him. Otherwise, he is often unflappable and chilled out.

Physical Appearance

Slumbo is mostly light blue. His body, which also acts as his face, is a tapered down shape, with half-open eyes resting on top. There is a black stripe on the very top of his body, on which rests a light blue ice crystal on the middle. He has an underbite containing three sharp teeth. He has a darker blue fin-like extension on his back. His arms are dark blue and long, with black markings on the tops and bottoms. His hands are made of mitten-like jagged ice crystals. His legs are grey and short, with darker blue short feet with two light blue toes on each.


He has incredible strength, so he can hold large structures easily. He also has icy breath that can freeze things.

  • His ice claw pieces would later be used for Krog's icy eye.
  • From a side view, Slumbo's eyelids in animated form still resemble the helmets used to invoke them in his LEGO set.
