When it comes to traveling the ocean's currents, no one has as much fun as Crush. The 150-year-old sea turtle is young at heart with a laid-back surfer dude attitude that lets him go with the flow. But Crush is no drifter; he loves nothing more than the thrill of riding the rollicking East Australian Current (EAC) with his offspring. When Crush encounters Marlin and Dory, he's more than happy to help them find their way, provided they can hold on for the wildest ride of their lives.
Crush is a sea turtle who speaks in the manner of a surfer dude. He helps Marlin and Dory get to Sydney Harbour to rescue Nemo. His nickname for Marlin and Dory is "The Jellyman" and "Little Blue," respectively. After transporting Marlin and Dory on his shell to their destination and giving them the ride of their lives on the East Australian Current, Marlin asks Crush how old he his, and Crush replies, "150, dude, and still young!" Probably the best way to describe Crush is a surfer punk who loves and cares for his son, Squirt.
Crush returns in the sequel Finding Dory, this time as a minor character. In this sequel, he only makes a brief appearance where he and Squirt help Marlin, Dory, and Nemo get to Morro Bay, California in order to find Dory's parents Charlie and Jenny. While Marlin, Dory, and Nemo hang onto Crush, they arrive into their destination in a sunken wreckage where he and Squirt wish the three good luck into helping Dory find her missing parents. Crush and Squirt are never seen again throughout the rest of the film after they transport Marlin, Nemo, and Dory to their destination.
He appeared on the PBS Kids Go! show, FETCH! with Ruff Ruffman, in the season 5 episode "The Ol' Shell Game." In that episode, it is Crush's birthday, so Ruff gives him a call. During that call, Crush tells Ruff about trouble happening with turtles, so Ruff sends Marco and Shreya to learn about sea turtles. At the end of the episode, Crush thanks them for helping the sea turtles and says that it was the best birthday present ever.
Based on the fact that Crush's father is named Mr. Turtle, this would make Crush's full name Crush Turtle, or C. Turtle (sea turtle) for short.
It is implied that Crush's (and to a lesser extent, Squirt's and the other turtles') home is actually Hawaii, and he and the other turtles are using the EAC to return there.
According to the Guinness Book of World Records, sea turtles can actually live up to 152 years. This contradicts what Crush said about still being young at age 150, it could be possible that he feels young instead of literally young.
Crush makes a cameo appearance in the Pixar short Lava.
