The Even Bigger Slime Movie

Slimer (originally referred to as the Onionhead and sometimes the Mean Green Ghost and the Ugly Little Spud) is a character from the Ghostbusters franchise. Slimer is a green, gluttonous ghost that is the first successful catch of the newly formed Ghostbusters. He appears in the films Ghostbusters (1984), Ghostbusters II (1989), the remake Ghostbusters (2016), and Ghostbusters: Frozen Empire (2024), in the animated television series: The Real Ghostbusters, Slimer! and Extreme Ghostbusters, and in the video games: Ghostbusters: The Video Game (2009), Beeline's Ghostbusters (2013), Ghostbusters: Spirits Unleashed (2022) and Ghostbusters: Rise of the Ghost Lord (2024). Slimer was voiced by Ivan Reitman and Adam Ray in the films and by Frank Welker in the animated series. In The Real Ghostbusters, he is the Ghostbusters' mascot and friend. Ghostbusters: Afterlife (2021) instead features a similar ghost named "Muncher".
