Whale

The Whale is a minor character from Disney/Pixar's 2003 animated film, Finding Nemo.

Finding Nemo
In Finding Nemo, the whale is first seen from a distance before he reveals how large he is. Dory starts speaking whale to try and ask him if he can help them find Nemo, but the whale ends up swimming away. But then slowly (and rather ominously) he swims up behind Marlin and Dory (also scaring some Krill, who tell the two fish to swim away), and swallows Marlin and Dory whole. While Marlin struggles to get out, Dory tries to speak to the whale again. Marlin reluctantly trusts Dory and allows himself to be ejected from the whale's blowhole at the risk of being eaten. Fortunately, they are carried to Sydney Harbour in the process. The whale moans back to Dory, which she takes as its greeting, and thanks it for helping the duo.

Disney Parks
The whale appears in World of Color during the show's version of the sequence of Dory speaking whale and is the lead-in to the Pines of Rome sequence.

Trivia
|The Whale's Uvula (Circled)
 * One of Finding Nemo's crew members, head shader Robin Cooper, took photos inside a dead, beached gray whale in order to portray the inside of the whale accurately. In addition, while whales' mouths and blowholes aren't connected, director Andrew Stanton had to "defy reality" in order to move the plot, as the other ways that Marlin and Dory could escape from the whale weren't appetizing.
 * Blue whales have black baleen plates and tend to be larger. And while the whale has a uvula hanging above his soft palate, whales don't have uvulas at all. (However, this was an intentional mistake by the filmmakers, as they felt audiences would see that Marlin and Dory were inside the whale's mouth if it had a uvula as "stage dressing.")
