Into the Hatverse, later rereleased as Constance Gets Mugged, is the first episode of the unofficial The Haunted Mansion parody series Charlie's Head Is In The Hatbox, created by fan Rain N. Thirteen. It features a version of Constance Hatchaway, one of Madame Leota, and several versions of the Hatbox Ghost, including Charlie Hatfield, Horatio Ernest Topper, Egore Von Bite, Thomas Gracey, Randal Pace, and two other versions. Rain is also featured, and the local version of Ezra is mentioned.
- Madame Leota is capable of summoning ghosts across dimensions.
- Even after being summoned to this world, the various dimensionally-crossed Hatties continue to follow the ghost physics of their home worlds.
- Dialogue suggests that in Rain's World, ghosts cannot float through walls after they've fully materialized.
Into the Hatverse was first released without any series branding on Rain's Blog on Tumblr, before being rereleased on YouTube as Episode 1 of a wider fan project now entitled Charlie's Head Is In The Hatbox, in which instance it was retitled Constance Gets Mugged.
