Alice spends her day on the beach with her pet dog. After an old salt tells her a tale of a giant squid sinking his old ship, she falls asleep and dreams of sinking to the bottom of the ocean where she meets a colorful cast of cartoony fish, such as a family of literal "cat-fish", a threatening octopus, and a hungry giant herring.
Behind the scenes
This cartoon short was released in 1925 as a silent film and later re-released with sound. It is the first short in the Alice Comedies series (second if one chooses to count Alice's Wonderland). It is the first canonical story to take place in the Prime Universe.
