Dopefish Lives!

Taking its name from a secret message in Rise of the Triad, this game takes the famous ravenous green burping fish antagonist of the underwater levels of Commander Keen 4, the Dopefish, and, for the first time, takes him out beyond the role of easter egg and puts the player in charge of him. The player swims around the screen and opens the goofy fish's gaping maw by hitting the Ctrl key... hopefully timed appropriately for when a little schoolfish might just be swimming in (and then...indicating its appreciation with a resounding belch).

Upon consuming a certain allotment of fishies, levels proceed, first adding coral obstacles and then exploding mines. Still later levels feature the Sprite actively harassing the Dopefish. After sustaining three wounds, the meal is done!
