Twisted pebbles

(You were on floor 15, all your teammates died. And you hear pebbles footsteps? You hid behind a wall. And there’s pebbles, but he’s a mutated, corrupted Version of himself.. he now has long legs and tail, and his feet growed claws and he also has ears.. and his teeth are sharp.. his eyes are red. And then he saw you, then he started barking and running towards you.) “BARK ARF!” (You then hid from him, and he lost sight of you.) “grrr……” (pebbles is a dog btw)
