Spongebob: Battle For Bikini Bottom is a fun, easy game that you can just pick up and play when you're in the mood for some silliness. Spongebob and his pals engage in some fights with robots and occasionally other things like jellyfish, but it's just over the top and not graphic in the least. Spread throughout the game are puzzles and minigames, which probably won't challenge older kids or adults, but might be a little challenging for younger kids. Also of note is the game's open ended design, you can unlock several levels and complete them in whatever order you like, and you can even explore the main hub, which has many secrets and surprises.
The graphics faithfully capture the look of the show, though some of the characters look sort of ugly to be blunt. The music in the game is nothing special at all, but it won't grate on your nerves or anything. Some of it is even somewhat pleasant. Most of the voice actors from the show are here, and they do an amazing job. Usually in these video games based off of cartoons the characters are either voice by mediocre replacements or the actors sound dull, as if they're being forced to do this job. But that's not what's going on here, they sound happy and excited, just like in the cartoon. Mr.Krabs and Mermaid Man are voiced by different people, although the people doing their voices are OK.
Overall, this is a great game for kids and even older kids will probably have a good time playing it like I did. For those of you who are weary of these videogame adaptions of cartoons, which usually aren't very good, I can assure you this is definitely one of the best ones out there. There isn't anything offensive in this game, except for some mild cartoon violence as mentioned above. With that said, there's nothing particularly educational going on here, either. The best messages you could take of this game are the usuals: good always beats evil, always do your best to fix your mistakes, etc. But overall, this is a very enjoyable videogame.
