Mighty Mouse first appeared on September 9th, 2016 in a Google Hangouts call featuring a couple cast members from the Frightside crew. Mighty Mouse's relevance was brought up through the likes of Pale-Tuna to distract Moppy, Spilled Ketchup, Strongarms, and Shankre from loosing their shit over a game of Don't Starve Together; since then, nobody has really given a shit about him aside from Pale-Tuna.
