Construction on the carnival, alongside the Death Egg's repair work, was overseen by Dr. Eggman's assistant Dr. Snively while his boss was away working on other schemes.

Knuckles the Echidna later passed through Carnival Night Zone in pursuit of a fleeing Eggbot controlled by Dr. Snively after multiple encounters on the island.
