Snurfs

These are a conglomerate of tiny purple people from another dimension. While the species has several proper names, citizens of Halcyon City colloquially call them "Snurfs," after the children's television program and associated merchandise. Sales of Sugar Snurfs cereal have increased 72% since the discovery of the Purple People Gang.
Recently associated with known villains, they now reside in the walls of buildings in Halcyon city, performing maintainace work and other odd jobs.
