Movie where a boy befriends a mermaid and fights pirates

In this "half-fish" out-of-water animated adventure, a mermaid princess makes a bargain with a sea witch to become human.

The youngest of King Triton’s daughters, and the most defiant, Ariel longs to find out more about the world beyond the sea, and while visiting the surface, falls for the dashing Prince Eric. With mermaids forbidden to interact with humans, Ariel makes a deal with the evil sea witch, Ursula, which gives her a chance to experience life on land, but ultimately places her life – and her father’s crown – in jeopardy.

Two teenage girls discover that mermaids really do exist after a violent storm washes one ashore. The mermaid, a sassy creature named Aquamarine, is determined to prove to her father that real love exists, and enlists the girls' help in winning the heart of a handsome lifeguard.

The "liquefaction of the liquid" is taken to such extremes that as soon as the guttural singing of Mopcut begins, the image space is overcome with spectral flutters and untenable fluctuations.

In stifling Edwardian London, Wendy Darling mesmerizes her brothers every night with bedtime tales of swordplay, swashbuckling and the fearsome Captain Hook. But the children become the heroes of an even greater story, when Peter Pan flies into their nursery one night and leads them over moonlit rooftops through a galaxy of stars and to the lush jungles of Neverland.

Leaving the safety of their nursery behind, Wendy, Michael and John follow Peter Pan to a magical world where childhood lasts forever. But while in Neverland, the kids must face Captain Hook and foil his attempts to get rid of Peter for good.
