What’s even stranger than the Japanese urban legend of a malicious spirit that prowls public bathrooms offering its visitors red or blue toilet-paper is the fact that director Maarten Groen made a ridiculously good short film out of it. Arrêt Pipi, inspired by the Japanese tale of Aka Manto, skips exposition and jumps straight into the nightmare, letting the simplicity of two people coming face-to-face with a monster in a bathroom rule the short.

Impossible to look away from, Groen’s 6-minute short is a nasty piece of work and one that feels like it should be the opening scene to a feature film—I would happily watch that, by the way. Its razor-sharp narrative, set almost entirely in a bathroom stall, is executed brilliantly with its straightforward tale of terror kicking you right in the teeth.

Sarah and Bram’s roadtrip takes a horrifying turn when they stop for a bathroom break in the dark woods of Wallonia.

It stars Bo Maerten, Benjamin Moen, Poal Cairo and Pim Lambeau. Check it out below and find more short films like Arrêt Pipi by visiting the Short Round!
