 * The HUD is different with different graphics (such as shiny objects being a purple box, 2D underwear, 2D golden spatulas, and an unknown anchor).
 * There are very few sound effects
 * The only two music tracks are the APM songs "You're Nice" and "Leaf Blower".
 * The layout of the furniture in SpongeBob's house is different.
 * There is a smelly sundae on SpongeBob's chair.

 * Squidward is wearing his Krusty Krab employee's hat and is holding his clarinet.
 * Bikini Bottom has a lot more sand.
 * The Krusty Krab is larger, has no flags, and is textured differently.
 * A row of golden spatulas can be seen in front of the Krusty Krab.
 * The toll gate has a shell that says "stop" on it.
 * The prompt to enter the Krusty Krab is small, white, and isn't in a box. The unused Patrick's Dream has text like this when it says to enter Patrick's Mind.
 * Sandy's lasso makes a swish sound
 * Sandy says "Take that!" every time she uses the lasso.
 * It makes two different blinking sounds whenever something lands.
 * Instead of a glove, there is a green arrow that points to objects you can lasso.
 * The tikis aren't animated.
 * The shiny objects are random shapes.
 * Sandy slides on her tail instead of a shellboard.
 * SpongeBob's bubble moves look different. The Bubble Bounce has shoes instead of feet, and the Bubble Bash has a generic sports helmet instead of a viking helmet. The sound they make is also different.
 * The layout of the Flying Dutchman's Graveyard is slightly different.
 * The music seems to cycle between "You're Nice" and "Leaf Blower".

 * There are no taxi gates.
 * There are white urchins on the rocks in Jellyfish Fields.
 * The layout of Jellyfish Fields is slightly different.
 * The Bubble Bowl is just a normal ball.
 * The clam gates haven't been implemented yet, so it's just a box that says "Shiny Object Gate", looking similar to the temp texture.
 * The orange fish that gets hit by the Ham-Mer is behind the gate instead of up the mountain.
 * Patrick seems to be sparkling for some reason.
 * Patrick has a different walk cycle.
 * Larry is at the top of the slide instead of Mermaid Man.
 * The only voice acting whatsoever is Sandy saying "Take that!"
 * There is no lighting.

Several Nickelodeon games at the time advertised other Nick games. Some had trailers for Battle for Bikini Bottom that have a lot of clips of early gameplay. They share a lot of the same footage, but some have some footage the others don't.
