SCTV alumni Martin Short (as Wesley, a boy turned into a monster) and Eugene Levy (as Brian, a wisecracking brain in a jar) lend their voices to the animated adventure Creature Crunch, which — with its bright backgrounds, big-headed characters, and sloppy plotline — is reminiscent of the style of Ren & Stimpy creator John Kricfalusi. Creature Crunch is passably enjoyable, but the point-and-click action is ho-hum at best (the usual animated furniture and knickknacks) and puerile at worst (in one scene, hanging pieces of meat produce burps and farts that only kindergartners could find witty). This amounts to two vets marking time till they land cameos in the next Harold Ramis movie. C
