Approaching the multicolored funhouse, you see that it looks like a giant clown bent double with its laughing mouth being the entrance and its gloved hands holding the giant FUNHOUSE sign. As you put your ticket in the booth that looks like a giant clown shoe, you see a sign reading
PLEASE REMOVE SHOES AND SOCKS BEFORE ENTERING.
You don't see anything unusual about this, it's common practice with bouncy castles and the like. You leave your shoes next to thebooth and enter the Funhouse barefoot. As you pass through the mouth you look up and see the clown looking down on you.
Inside, you find yourself in a room with several crooked doors. Hearing a chomping noise, you turn to see a set of huge teeth come down over the entrance, sealing you in. It seems you have to choose one of these doors.
