Paula Diamonds arrives home to find a rocking horse in her living room with a tag attached that reads, "HAPPY BIRTHDAY PAULA!" She's confused. Her birthday isn't for another 7 months and this is clearly not a gift for a grown adult like Paula. And further, how did it get into her house?! So creepy. Paula leaves the horse in the living room and walks away, creeped out. The next day Paula is relaxing on the sofa with the horse nearby when out of the corner of her eye, she thinks she can see the horse move! Surely, she's imagining things. She goes back to her phone, but moments later it rocks again and then moments after that, it begins to move a third time! Paula finds herself in a trance, drawn to the rocking horse. She can't resist it. She gets on and begins to rock. Suddenly, she snaps out of her trance. A giant teddy bear and stuffed pony appear and her speech has regressed. Her mental state is slowly regressing back in time as she rocks. The more she rocks, the more strange objects appear and the further back her mental regression goes. Eventually, she's regressed all the way back to diapers. She plays with her toys and giggles. Suddenly, she has to go potty! Good thing she's wearing a diaper since Paula is no longer potty trained!
