Just keep swimming! We loved Dori and her forgetfulness (how many of us can relate to that)! Nemo’s journey begins once he ventures into the open sea despite his father’s constant warnings of the dangers. He is captured in the Great Barrier Reef and taken to Sydney, where he is kept in a dentist’s office. His timid father, Marlin, stops at nothing to rescue his son and meets Dori, sea turtles and all sorts of other fish, including sharks, on the way.
