slink around
to creep or slither around furtively. The cat slunk around, waiting for a chance to get at the bird. Don't slink around like that. Someone is likely to take you for a robber.

to creep into something. The cat slunk into the hallway and lay down in the middle of the floor. I left the door ajar and a cat slunk in.
slink off

slink out (of some place)
to creep out of some place furtively. The fox slunk out of the henhouse just as the farmer came out. It slunk out and got away.
