My Singing Monsters, the music-building mobile game from Big Blue Bubble, first launched in 2012 and lets players collect monsters that each sing a different part of an island's song. Cold Island is one of the game's early snowy islands, and the Wubbox is its large, box-shaped monster whose electronic voice gives the island a distinctive robotic layer. Clips of individual monster parts became popular as fans shared favourite island songs, compared versions, and reused short sections in edits. The Wubbox's Cold Island part remains a recognisable favourite because it is short, melodic, and instantly tied to that island.
