I was searching for items in Level 0, and this thing dashed by me. New entity? (pitshost)

DAY 14: OMFG I MANAGED TO GET TO LEVEL 3999! All i have to do is to grab the task board and- oh. my task is to speedrun the entire backrooms. WELL THIS IS GONNA TAKE LONG.
Update: Jesus christ it took 5:00 minutes I'm a f**king fast
