Slumbo is a Frosticons Mixel and also Ceylan's second partner.
It takes an earthquake to wake this guy up, believe it or not. But when Slumbo is awake, this lazy Frosticon has the muscle to move giant objects and make obstacles for Nixels. But beware, Slumbo can get a brain freeze from making ice tunnels. He falls asleep at the most inopportune times, like mid-way through lunch or while falling off the side of a cliff.
