The 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.
Variants
There are some episodes or scenes in episodes where the bubble transition is replaced with another transition effect.
In "Ripped Pants," the screen rips apart right after the scene with Template:Data:Links pretending to drown, promptly annoying everyone.
In "Sleepy Time," after Dream Gary says "come," a wipe transition is used.
In "Suds," in the montage of Template:Data:Links 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 "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 Template:Data:Links 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.
"Rock Bottom" is the only episode to end with a bubble transition.
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 "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 "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" and certain Template:Data:Links episodes, a different sound effect is used for the bubble transitions.
