The film features no LGBTQ+ characters or themes, focusing instead on themes of kindness and emotional growth in an underwater adventure suitable for young children.

The film contains no portrayal of transgender characters or themes, focusing instead on an underwater adventure promoting friendship and kindness among sea creatures.

Female characters including Pip, Marin, Shimmer, and the dolphins participate in the story's adventures but engage in no physical combat. Conflicts involve helping sea creatures and non-violent resolutions like removing kelp and countering hypnosis, with no instances of female characters defeating male opponents in close-quarters fights.

The 2026 animated film adapts the children's book series without altering the genders of established characters like Mr. Fish, who remains male. New characters such as Pip and Marin are original additions with their own genders, not swaps from prior canon.

The film features anthropomorphic sea creatures from the source book, which establishes no racial identities for the characters. Voice casting by diverse actors does not constitute a race swap under the definition.
