SpongeBob's block is more of a dodge, as he crouches instead of just blocking, which he can dodge a lot of projectiles. However Patrick's (pink) and Larry's (volleyball) projectiles cannot be dodged by him.
In tournament mode, at the start of each round, Plankton is seen laughing and jumping into the robot's head, which opens and closes. This idea may be taken from the Street Fighter II series when M. Bison (the final boss), at the start of round 1, does the animation where he flings and takes off his cape.
At first, Larry the Lobster and Mr. Krabs are locked in the character selection. The only way of unlocking these two characters is by completing tournament mode.
Plankton's voice clips are used from episode "Plankton!."
