The game begins with the narrator (voiced by Will Stamper) telling the adventures of the hundreds of friends aboard the S.S. Friendship, as well as Hatty Hattington, who is known as "best friend to one and all". After encountering a heavy storm, the S.S. Friendship becomes shipwrecked on a mysterious, seemingly abandoned island, whereupon most of the friends go missing. Upon waking up from the wreck, the
player character seeks shelter from the storm in a dilapidated theater. Upon coming to, it is revealed that the entire crew of the S.S. Friendship is being held prisoner by cats, with Hatty, wearing a glowing
top hat, as their apparent new leader. The player is then released from their cell and forced into deadly games by the feline wardens. As the player completes challenges, they find gems which are spent on unlocking fellow crew members to play as in these theater performances. Appearing to be possessed by the hat's unknown powers, Hatty begins working for the cats and against the player. As the player progresses, the narrator reveals more about the theater. Hundreds of years before the player got shipwrecked on the island, Purrham Furbottom, a theatrical aficionado, sought to build the world's greatest theater. The opening night saw the most jaw-dropping feats and thrills the likes of which were never seen before, making the theater an overnight success. However, Furbottom did not allow intermissions in the theater, and after an untold amount of time watching the show, he died after "pooping himself to death on the way to the bathroom." Since then, his top hat has been passed down to various others, who were each revered by the cats as their leader, and who each met with grim fates of their own. The hat, the narrator theorizes, is haunted by the grief and sorrow of each of its past wearers, and Hatty is its current victim, having sunk into a depression while being surrounded by the many gems the player has accrued, without doing anything to help the state of the theater. Eventually, the cats grow tired of Hatty's inaction, and begin rioting, striking, and more, while the player's challenges grow increasingly difficult. As the theater deteriorates further, the narrator provides encouragement to the player and continues to shed light on the cats' mental state, which grows more unstable as time progresses. The narrator also instructs the player to enter The Vault, which houses Hatty and all the gems the player has spent, before the cats kill Hatty and the rest of the crew, starting the madness over again. After completing the final set of challenges inside the Vault, the player breaks into Hatty's throne room. Hatty does not budge, so the player carries him out of the crumbling theater as the crew of the S.S. Friendship orchestrates a mass breakout. Everyone manages to make it back to the boat amidst the chaos, escaping the island and the cats that reside there. The cats try to foil the player's escape, but are shot by the others with guns. As the player celebrates with hot cocoa on the ship, they try to cheer up Hatty, who the narrator says that he would not move, blink, respond to hugs, or talk. He also asks "Where has he gone to? Where?", referring back to Hatty's death during the riot at The Vault. The narrator sings a sad song as the credits roll, before quickly recovering and singing a nonsensical, upbeat song, rocking the boat and flinging Hatty into the sea, where he sinks to the bottom. The hat lands on his head and begins glowing green as opposed to its usual red, and shoots a beam skyward, where it sends the boat flying and continues into space, where it vaporizes
Alien Hominid from the game of the same name and a bear that appeared during the narrator's upbeat song, foreshadowing the events of
Pit People. The narrator claims to understand what just happened but does not explain, sending the game back to the title screen. ==Development==
