Bubble transitions, also known as bubble wipes, are a recurring element of SpongeBob SquarePants episodes. They are a transition effect that show copious amounts of bubbles floating up from the bottom of the screen as the scene the transition plays on cuts to the next scene.
There are some episodes or scenes in episodes where the bubble transition is replaced with another transition effect.
- In "Tea at the Treedome," after Patrick says "They should call you SpongeBob FancyPants," the screen wipes.
- In "Ripped Pants," the screen rips apart right after the scene with SpongeBob pretending to drown, promptly annoying everyone.
- In "Jellyfishing," the only transitions used in the episode are fades.
- In "Boating School," after SpongeBob says "Mrs. Puff, I think I cheated." the screen fades to black and then fades back from black when Mrs. Puff is getting carried in an ambulance.
- In "Sleepy Time," after Dream Gary says "come," a wipe transition is used.
- In "I Was a Teenage Gary," a wipe transition is used after Squidward is injected with snail plasma.
- In "Suds," in the montage of Patrick trying to treat SpongeBob, the transition from one treatment to another treatment is pink bubbles representing bubbles caused by the suds appearing and popping.
- In "Valentine's Day," they are replaced with hearts.
- In "Texas," they are replaced with a page turning like the scene was a page in a book.
- In "Prehibernation Week," they are replaced with SpongeBob and Sandy doing extreme sports during the extreme sporting games.
- In "Greasy Buffoons," the transitioning bubbles are replaced with grease.
- In "Planet of the Jellyfish," the first transition bubble is replaced with Jelliens.
- In "It's a SpongeBob Christmas!," the transitioning bubbles are replaced with snowflakes and one transitioning scene with coal.
- In "Squid Defense," karate chop transitions are used instead of the regular transitions.
- In "SpongeBob's Place," after Mr. Krabs builds a trench filled with molten lava near the Krusty Krab door, the customers step over him to go to SpongeBob's Place. After Krabs' plan to keep his customers backfires, the transitioning bubbles to the next scene are replaced with the lava bubbles.
- In "There's a Sponge in My Soup," the transitioning bubbles are replaced with paisleys.
- In "Stormy Weather," the transitioning bubbles are replaced with raindrops.
- In "Mind the Gap," the transitioning bubbles are replaced with bubble notes.
- In "There Will Be Grease," the transitioning bubbles are replaced with bottles of Everything Juice.
- In "Patrick the Mailman," the transitioning bubbles are replaced with snowflakes.
- "Reef Blower," "Krusty Krab Training Video," and "Boat Smarts" are the only episodes without any bubble transitions, even in the opening credits. "The Camping Episode" and "Bubblestand" also do not feature any bubble transitions, not counting after the opening credits. "Help Wanted" and "SB-129" have only one bubble transition.
- "Rock Bottom" is the only episode to end with a bubble transition.
- In some earlier episodes, text can mistakenly be seen at the bottom of the screen during bubble transitions:
- In "Squidville," for a brief second, a bubble transition is shown and "Rough Draft Korea" appears at the bottom of the screen. This error was made by Rough Draft Studios in South Korea where they animate the episode. Also, it mentions a date ("DATE: 08 / 30 / 00"; August 30, 2000), which is when this episode was in the process of being animated by Rough Draft Studios.
- In "Chocolate with Nuts," for a brief second, a bubble transition was shown with a date of Friday, September 14, 2001 at the bottom of the screen.
- In "SpongeBob Meets the Strangler," for a brief second, a bubble transition was shown with Rough Draft Korea and a date of Friday, May 17, 2002 at the bottom of the screen.
- In "Have You Seen This Snail?," for a brief second, a bubble transition was shown with Rough Draft Korea at the bottom of the screen.
- In "Skill Crane," for a brief second, a bubble transition was shown with Rough Draft Korea at the bottom of the screen.
- In "Born to Be Wild," SpongeBob breaks the fourth wall by riding on a bubble transition.
- In "Truth or Square" and all episodes since "Extreme Spots," the transitions were updated with slightly fewer bubbles and are larger in order to fit the 720p/1080i high-definition screen.
- In "Truth or Square," as well as certain season 9 and 13 episodes, a different sound effect is used for the bubble transitions.
- "Tutor Sauce" has 14 bubble transitions, the most out of any episode, beating "License to Milkshake" with 13.
- The bubble transitions also appear in the Finny the Shark TV series, but this time, the bubbles float from left to right instead of bottom to top.
