List of episodes that started at Spümcø that were later finished by Games Animation Inc.

This is a list of episodes that have started off in production by Spümcø, but were later finished by Games Animations Inc. (nowadays called Nickelodeon Animation Studios in later years) after John Kricfalusi and his crew of Spümcø have been known to be fired after "Man's Best Friend".

Season 2

Despite being a Spümcø season like season one, some episodes were later finished off by Nickelodeon after the firings of John and his Spümcø crew on September 1992.

Episodes

1. Sven Hoek - Games Animation made an intro for the beginning of the episode instead of using a title card, and the music was added into the episode which was used for Sven's character theme. Billy West voiced for Ren during the Farewell Segment, which marks the first episode that Ren is voiced by both John Kricfalusi and Billy West.
2. Haunted House - The episode was originally written for an episode of Tiny Toon Adventures before being scrapped and used for The Ren & Stimpy Show. The animation arrived during the final week when the show was still at Spümcø. It was eventually finished by Games Animation during post-production.
3. Mad Dog Hoek - This episode was still being animated by Rough Draft when production shifted from Spümcø to Games Animation.
4. Big Baby Scam - Originally, Old Man Hunger was going to whistle an original tune by recorded by John himself, however, when Games Animations did the sound mixing for this episode, they chose to have Old Man Hunger whistle "In The Hall Of The Mountain King" rather than John K's original tune. This was also still being animated by Rough Draft when production shifted from Spümcø to Games Animation.
5. Son of Stimpy - During production of the episode, it was sent to Carbunkle Cartoons as the transition from Spümcø to Games Animation occurred, and was eventually finished during post-production.
6. Monkey See, Monkey Don't - This episode was drafted at Spümcø and finished off by Games, in which it's the first 11-minute episode that Ren is voiced by Billy West.
7. Fake Dad - The episode was originally planned as a 22-minute special episode during production at Spümcø. After John K was fired, Games Animation initially planned to keep in a sequence that had Kowalski playing football with Ren and Stimpy, with new animation while having the timing and pacing made with what John K wished for. However it was eventually cut down to an 11-minute episode, as Jim Ballantine found the sequence to be boring. It was later paired up with "Out West".
8. The Great Outdoors - John voiced some recordings for characters such as Mrs. Buttloaves, Mr. Horse, and Old Man Hunger in this episode before his firing from Nickelodeon. However, he doesn't voice Ren in this episode, only three characters is what he recorded his voice with. These were recorded in production before his contract termination.
9. The Cat That Laid the Golden Hairball - Billy West voices Ren instead of John. However, John's recording of Ren crying can be heard when he's upset about Stimpy appearing close to death.
10. Stimpy's Fan Club - Despite being finished at Spümcø, the oath segment was drafted at Spümcø and was later finished at Games with Ren being voiced by Billy instead of John in said segment. However, parts one and two of the episode are the only parts of the entire episode where Ren is voiced by John Kricfalusi.
11. A Visit To Anthony - Although John voices Ren in this episode, he's briefly voiced by Billy West in the eye bulging scene. Anthony's dad had his voice acting recorded after it was switched to Games Animation.
12. The Royal Canadian Kilted Yaksmen - Despite Ren being voiced by John in this episode, he was voiced by Billy during the ending song, which was also a scene done by Games Animation, "The Royal Anthem of the Kilted Yaksmen".

Season 3

This season is the first to have episodes drafted from Spümcø to be later finished by Games Animations Inc.

Episodes

1. To Salve And Salve Not - This episode had its story done by Bob Camp and Vincent Waller at Spümcø. It was eventually held over for a third season at Games Animation.
2. A Yard Too Far - This episode was originally from Spümcø, where it was written by John K. himself, but Nickelodeon decided to bring this episode for the show's third season to finish it after John's firing along with the Spümcø crew. However, John K. was left uncredited.
3. No Pants Today - It was another episode drafted from Spümcø and was finished by Games. However, the animations were the same from season two and season one because of the storyboard being completed from production.
4. Ren's Pecs - This episode was written by Richard Pursel at Spümcø before it was switched and eventually later finished by Games Animation, after John's firing along with the Spümcø crew.
5. Stimpy's Cartoon Show - This episode was written by John Kricfalusi for the show's third season. However, Ren's crying sounds from "Stimpy's Big Day" is reused. John Kricfalusi's role as Ren from past episodes were used again as an Easter Egg reference to certain episodes from season two, but they're high pitched to sound like Billy West's voice acting for Ren, with the episode itself was completed by Games Animation Inc. The animations are different from Spümcø's, even though, the episode was planned from Spümcø to Games. The entire episode was animated in digital ink and paint like other episodes from season two instead of using traditional cel. However, the segment, "Flod" used traditional cel and was possibly finished by Spümcø or Games, one of the two at least.
6. Jimminy Lummox - The premise segment of this episode was written by Bob Camp at Spümcø. It was, however, rejected before being revived for the third season after production switched to Games Animation Inc.
7. Bass Masters - The premise segment of the episode was written by John K. and Richard Pursel at Spümcø, before they were fired when it switched to Games Animation Inc.
8. Eat My Cookies - The idea was originally a story by Richard Pursel during Spümcø. After it was switched to Games Animation, the story was heavily rewritten by Ron Hauge, with Richard Pursel's credit as a writer of the episode removed in the opening titles, although he would be credited for the story at the end credits.
9. Lair Of The Lummox - This is another episode written by John Kricfalusi and made for Spümcø. However, storyboards and animation writing were completed before Spümcø/John's firing from Nickelodeon. It was going to be made by Spümcø, but Games Animation Inc. took over for John/Spümcø and the episode was produced then pitched for the third season. It was originally produced to be the fifth episode of season three, but it was later put on as the season three finale.

Season 4

Episodes

1. Magical Golden Singing Cheeses - The episode was originally written by John K. and Jim Gomez for season 1, but was rejected though. During Season 4, they came across the story and heavily reworked the episode. According to John himself, it was mostly the same except it was "slower" than preferred, plus the giant underground was originally going to be a Lummox that was mostly cramped in space instead.

Season 5

Episodes

1. Ren's Brain - Ren's brain saying "You eediots!" in the end of the episode is taken directly from "Sven Hoek", which was said and voice recorded by John Kricfalusi himself when he was voicing Ren for "Sven Hoek", in which, the past line was used as a sound clip at the end.
2. Who's Stupid Now? - This episode was originally going to be called "The Big Switch" for the original show, but it was changed to "Who's Stupid Now?" for an odd reason. However, after the original series ended from 1995 to 1996, there was going to be an episode for the adult-oriented reboot with the same original title from said episode, but with an alternately loosely based off plot from the original episode Games finished off at. However, this reimagined version for Adult Party Cartoon was never finished and primarily scrapped due to the spin-off's cancellation after complaints from fans of the old show.
3. Terminal Stimpy - The episode was originally idea by Richard Pursel written at Spümcø, though it was later finished by Games Animation after several revisions of the episode. However, unlike "Eat My Cookies", Richard Pursel wasn't credited in both the opening and ending credits for this episode altogether.
