Spikefang

(You were in door 150, until you see a big hole. But randomly, a black furry figure comes out of the hole. Its appearance is a black figure with spiked-arms, no eyes, and it also has a long snout with sharp teeth inside. And it can somehow see without eyes. And it also has long-scretched ears. And it also has black fur, then it randomly saw you. And starts roaring, sharp teeth revealed, and it starts running towards you. It is incredibly fast somehow.)
