Ball Room Clip
From Battle for Bikini Bottom
Trapped within a glass dome is a golden spatula. Though normally only accessible through completing a Rube Goldbergian puzzle, this spatula can be collected much quicker while speedrunning.
L-Bowl (Without Ball)
By wedging SpongeBob between the glass dome and the adjacent metal wall while facing a specific angle, the player can perform an L-Bowl while being displaced. This, in turn, changes the direction of the displacement to where SpongeBob is facing while simultaneously using the intangibility granted by the L press to clip through the cage.
L-Bowl (With Ball)
By derailing the ball towards the cage, you can clip into the ball, smash yourself between the cage and the ball, perform an L-Bowl, and skip the rolling ball challenge.
By derailing the ball towards the cage, you can clip into the ball, bring it around the cage next to Mr. Krabs, then L-Clip into the spatula's cage, skipping the rolling ball challenge.
