Bunger first appeared in Bugsnax, the 2020 adventure game by Young Horses where players catch food-based creatures on Snaktooth Island. Half burger and half beetle, Bunger speaks only by repeating its name in different tones, and this excited version plays when it charges, often chasing the player for ketchup. Clips and voice lines from the game spread through gaming videos, streams and meme edits, and Bunger's distinct burger design and squeaky voice made it one of the most recognizable and quoted Bugsnax creatures.
