Trouble is afoot in Bikini Bottom. The top-secret recipe for Krabby Patties has been stolen, and it is up to SpongeBob and Plankton to join forces on a trip through time and space to retreive it, or else Bikini Bottom will be forever stuck in a post-apocalyptic nightmare. Yes, it's a simple adversaries-join-forces-and-go-on-a-journey plot, but it works – what matters most in a SpongeBob film are the jokes. And just as you'd expect, the jokes come thick and fast.
The culprit turns out to be a pirate, Burger Beard (Banderas) and a portion of the film sees Bob and pals leave the sea for land, becoming 3D CGI characters in the real world. It's a nice twist and it works well, but the real strength here is the smartness of the animated hour that has come before, full of zany gags and wonderful comic timing. Throw in a time-travel twist and a cosmic dolphin overseer and you've got a colourful, wacky adventure that will keep SpongeBob fans of all ages very happy indeed – and is sure to win him some new ones.
