S4·E2 Gorillia

Stanley the gorilla escapes from Renford Safari Park, but the Rejects think it's just Ben in his gorillagram suit and put Stanley in goal in a match against the Razors. When the match is abandoned due to the ape, Stoker decides to get his own back and scare the Rejects with his own gorilla suit. It all backfires on him when the keepers from the safari park come to recapture Stanley.
