When Caro and Marce go on vacation they find a new friend, Buji, and just like Dibu, she is a cartoon animated kid. Abu, Pepe, Víctor, Leo and Dibu are left alone at home and they have quite an adventure when they decide to sign-up Dibu in a go-cart race.

Facing an imminent attack from Mars, planet Earth sends Dibu to Mars as a peace ambassador -- the only hope for averting the attack. Amazingly, he finds a friendly population, whose only issue is that they are fed up of their planet being used as a nuclear dump site. Besides averting the Martian attack, Dibu also inadvertently manages the save hit planet from the diabolical designs of an ambitious general

The evil Nasty comes to our world with two objectives -- kidnap Buji, and carry as much candy as possible back to his world. He has the ability to 'shape-shift', and using the appearance of Dibu, he holds up a bank so that he can get enough money to buy the candy. The police wrongly imprison Dibu, who manages to escape and confront Nasty.
