The Deep was one of the areas in Kart Kingdom. The area was themed of a coral reef underwater and is home to Clanky Caverns. It had a filter that slightly distorted the visuals to give the illusion of being underwater. It used to be the third area players unlocked until the April 2018 update that made all areas accessible upon joining. Whenever there was an event that asked players to use the Kart Studio to submit designs on the blog (after the Ruff Ruffman Event), that feature could be found in the Deep.
