The ride is themed to Disney-Pixar's Finding Nemo film, and named after Crush, a green sea turtle voiced by Andrew Stanton from the movie.

On August 27, 2021, following Disneyland Paris' reopening, Walt Disney Studios Park announced that the attraction was set to become part of the Worlds of Pixar area.

Guests enter the Toon Backlot of Toon Studio and stumble upon the beached sound stage and film set of Disney·Pixar's Finding Nemo, themed as Sydney Harbour, where Crush and his sea friends invite guests to climb aboard turtle shells for a ride through memorable scenes from the movie.

The second part of the ride's track is a faster rollercoaster in the dark, representing the spiraling, churning East Australian Current itself.

In a bid to decrease the long queues that frequently plague the ride, Disney conducted preliminary tests during July 2008 at the Crush's Coaster site to investigate the possibility of installing a Fastpass system at the attraction.
