This is a sub-page of SpongeBob SquarePants: Battle for Bikini Bottom (GameCube, PlayStation 2, Xbox).
Most of the NPCs in Battle for Bikini Bottom have walking animations despite never using them at any point; instead, they stand in the same place throughout the entire game. This suggests that the NPCs were meant to pace around rather then stand in one place. In addition to these unused walking cycles, there are also some other idle animations for the NPCs and bosses that are never seen in-game.
NPCs#

Mermaid Man#

An unused walking animation.

Mermaid Man running away from something, similar to Mrs. Puff.
Barnacle Boy#

An unused walking animation.
Plankton#
An unused walking animation for Plankton. The last few frames have him moving oddly, suggesting that the animation is unfinished.
Sandy#

Sandy has an NPC pain animation that cannot normally be seen. It cannot be triggered in the Treedome level, as the Sandy NPC there has a different model. It can be seen in the unused Robo-SpongeBob phase.

In the unused Patrick's Dream level, there is an unused idle animation of Sandy doing push-ups not present anywhere else.
Mime#

An unused animation for hitting the mime outside the Krusty Krab. This is impossible in-game, as he's outside of the player's range behind the glass.
Enemies and Bosses#
Ham-Mer#

An early version of the Ham-Mer's attack animation found in the early Goo Lagoon levels. It's slower and less cartoonishly exaggerated than the final animation.
Arf#

A very unfinished early version of the Arf's attack animation. This animation can be seen being used in the background of the IGN prerelease footaɡe.

There is also an animation for when the Arf gets lassoed by Sandy. Arf can never be encountered when playing as Sandy, causing this animation to go unused.
Robo-Patrick#

An unused idle animation.

Watch on YouTubeA few alternate idle animations for the unused "MuscleBob" boss, where he flexes and kisses his Anchor Arms. There's a variant of this animation where MuscleBob's arms have been deflated. There are also animations for a "Rumble" taunt, where MuscleBob slams his chest repeatedly. It also has a variant without muscles.
