Disney/Pixar's Finding Nemo features two main storylines. As in the 2003 animated feature film, the clown fish Nemo is headed for his first day at school when he's captured near Australia's Great Barrier Reef by a scuba diver and winds up in an aquarium in a dentist's office. In the first storyline, players take the role of Nemo's father, Marlin, who with the assistance of a forgetful Regal Blue Tang fish named Dory, must solve puzzles and master arcade-style mini-games in their search for his missing son. The second storyline involves Nemo's attempts to become friends with the other inhabitants of the aquarium in order to join the Tank Gang and help pull off their secret escape plan. Players can switch between the two storylines at anytime during the adventure until the two are united.
