Story
On a trip at the beach, Ben discovers a new alien form, named "Ditto". Ben discovers Ditto's power, the ability is he can make his own clones, and ditto can multiply himself anytime. Ben was playing a bit with the Ditto form, when a giant mutated seagull from Dr. Animo appears. It tries to snatch Ben and it succesfully snatches one Ditto and took him to a sunken ship. Dr. Animo tells Ben's clone that he wants to have the Omnitrix aliens DNA so that he can copy it to his mutated animals.

Back in the beach, the Ditto's Omnitrix insigna beeps but they fail to transform back to Ben's Real Look, because if there is another Ditto that is far from the other Ditto, Ben Could not transform Back, until the other Ditto is Close to the other Dittos.

The other Ditto Clone is taken to Dr.Animo's Lab in the sunken ship in the middle of the sea. Gwen, the other 3 Dittos, and Grandpa Max tried to find the other Ditto and bring it back. They work together until they found Dr. Animo's Ship. The Ditto Clone in Dr. Animo's lab was using Dr.Animo's Big Animal to get out from the lab, but still, Dr.Animo has the Ditto clone's DNA.But when the Ditto clones get Closer, Ben Transforms Back. When Dr. Animo shows his Stinkflies (he Gets the DNA from the Omnitrix) Dr. Animo Attacks them, and flees from the area, Ben transforms into Upgrade, the Tow Machine streches Upgrade's Liquid-Like Body and Ben got hurt. Fortunately, Gwen stops the Tow Machine using her magic. Ben then hi-jack a machine and sucessfully shuts the machines down (his time is running out), and he transforms back to his human form.

Ben seems to be not quite satisfied yet, he transforms again into Ditto to defeat Dr. Animo's Stinkflies and Dr.Animo by multiplying himself into lots of Dittos, thus defeating Dr. Animo and Dr. Animo is captured by the police.
