Jimmy Neutron is a boy inventor living in the colourful community of Retroville, USA, who pilots his own rocketship and has a pet robot-dog called Goddard - after the rocket scientist Robert H Goddard, one of the cartoon's few nods to an adult audience. The communications satellite that Jimmy has fashioned out of a toaster alerts hostile aliens to the presence of his home town, and after Jimmy and his pals have snuck out to an amusement park, they return to find that all of the grown-ups have been spirited away by the Yookians - an odd, poultry-worshipping race. In an inspired conceit, Jimmy turns the rides from the amusement park into a fleet of rocketships which he and his friends use to pursue the aliens to their home planet. Very obviously aimed at youngsters, this lively cartoon adventure has less to keep grown-ups amused than Shrek or Monsters, Inc, but nevertheless makes an attractive addition to the recent spate of popular animated features.

Jimmy Neutron is a boy genius and way ahead of his friends, but when it comes to being cool, he's a little behind. All until one day when his parents, and parents all over Earth are kidnapped by aliens, it's up to him to lead all the children of the world to rescue their parents.
