The Cherubs briefly appeared in the episode "City of Thieves" and played a short tune before stealing two sai from Finn, much to his surprise.
The Cherubs appear as small grey humanoid children with wings used to fly. One carries a bugle, the other a lyre. They look similar to modern depictions of Cupid.
- The Cherubs are actually putti, which are often confused with true cherubim, which look very different.
