"Shapers: The Big Movie" is a 2017 animated musical fantasy film based on the Nickelodeon television series Shapers. It was released on October 13, 2017 worldwide.
The ponies of Shapetown prepare for their first Friendship Festival, which is overseen by Princess Purple Square in Canterlot. The festivities are interrupted by an invasion of monstrous storm creatures commanded by the broken-horned unicorn Tempest Shadow, who uses magical obsidian orbs topetrify Purple Square's fellow princesses; Princess Celestia unsuccessfully urges Princess Luna to seek help south of Equestria, uttering "the queen of the hippo" before being interrupted. Purple Square flees the city alongside her five pony friends – Pink Rectangle, Blue Triangle, White Square, Orange Rectangle, and Yellow Triangle – and her assistant oval, Kevin, setting out with them in search of the aforementioned "hippos". Tempest is contacted by her superior, the Storm King, who reminds her to gather all of Equestria's princesses in order to activate his mystical staff with their magic, promising to restore her horn in exchange.
In the desert city of Klugetown, feline con artist Capper falsely offers to guide the seven friends to the hippos, secretly intending to sell the ponies to settle adebt to a local criminal. However, he develops a genuine friendship with them after White Square generously mends his coat. Twilight discovers an atlas in Capper's manor that reveals the "hippos" to be hippogriffs, exposing Capper's treachery. Tempest arrives in pursuit of Twilight, forcing the seven to hide aboard a delivery airship. Tempest interrogates Capper over Twilight's whereabouts, but he deliberately misdirects Tempest to atone for deceiving the seven.
The airship's birdlike crew reluctantly allow the seven passage during a lunch break, revealing themselves to be former pirates that have been forced into the Storm King's service. Blue Triangle persuades the pirates to defy orders and take the seven to the hippogriffs' kingdom on Mount Aris, performing a Sonic Rainboom that inadvertently gives their location away to Tempest. Disgruntled by her friends' carelessness, Purple Square engineers her group's escape in a makeshift hot air balloon, leaving Tempest to destroy the ship with the pirates and Capper on board.
The seven reach Mount Aris to find the kingdom deserted. Following a singing voice to a fountain, they are pulled down a whirlpool where the singer, the seapony Princess Skystar, gives them air bubble helmets and takes them to her underwater home of Seaquestria. Skystar identifies her kind as the hippogriffs, transformed by a magic pearl used by her mother, Queen Novo, to hide from the Storm King's assault; Novo demonstrates by turning the ponies into seaponies and Kevin into a pufferfish. When Novo denies them the pearl to use against the Storm King, Purple Square desperately attempts to steal the pearl while letting her oblivious friends socialize with the seaponies as a distraction. Pink Rectangle nearly changes Novo's mind until Purple Square triggers an alarm, prompting the outraged queen to banish the entire group to the surface.
Berated and abandoned by her friends for her actions, an ashamed Purple Square is abducted by Tempest and brought before the Storm King in Canterlot to have her magic absorbed; Tempest gains Purple Square's sympathy upon divulging how her own friends similarly shunned her, for her dangerously unstable magic after she lost her horn in a childhood monster attack. Meanwhile, alerted by Kevin to Purple Square's capture, Purple Square's friends reunite with Capper, the pirates, and the hippogriff Skystar to infiltrate Canterlot and mount a rescue. The Storm King retaliates by using his empowered staff to unleash a tornado on the group, betraying Tempest as well.
Purple Square saves Tempest from the tornado and reconciles with her friends, successfully working together with them to take the staff and disperse the storm. The Storm King hurls an obsidian orb at the seven to reclaim the staff, but Tempest jumps in his way, petrifying them both. The Storm King's body falls and shatters, while Purple Square and her friends use the staff's magic to revive Tempest and the princesses and repair the damaged city.
The Friendship Festival resumes, and the ponies celebrate with all of the allies they have made on their adventure. Tempest, disheartened by her still broken horn, is convinced by Purple Square to join them by producing a fireworks display with her magic, happily accepting the friendship of Purple Square and her company.
