Colbys parents brought Colby to an 'amusement park' (it's actually a lab) they were walking around when his parents "were going to toilets just wait here okay" Colby nods. After 30 minutes they weren't back so Colby just walked around he bummed into someone and he apologized but that was 'amusement park worker' (a lab worker) and they brought him to a lab room and locked the door to the isolated room the room said experiment 023 a little later they brought his parents there
