Pearl is a pink flapjack octopus in Finding Nemo. She says she has one shorter tentacle than the rest, though this is barely noticeable. She is pink like her father, but unlike him, her face is positioned in the middle. She also claims to be able to walk on land. Whenever she gets nervous or scared, she squirts her squid ink, or "inks" as she calls it.
One of Mr. Ray's students, Nemo meets Pearl and her friends, Tad and Sheldon, while waiting to start school. She was part of the group who saw the boat. Like the other children, she tries to see how close to it she can swim. When the diver appears, she flees with the rest of the class.
She briefly appears at the end of the film, welcoming Nemo and newcomer Squirt into the class.
Whenever she is startled, she releases ink (or "inks"). This trait was presumably inherited from her father, who has a similar release of ink when he encounters Bruce and his fellowsharks.
