Marmaduke traded away his owner-lady's vacuum cleaner. He traded it away for some bones, then hid the bones in the closet where his owner-lady used to keep her vacuum cleaner.

Marmaduke is chewing on one of the bones now. His owner-lady is looking in the closet, having just discovered that Marmaduke traded away her vacuum cleaner, for some bones. She is beginning to confront him about what he has done (trade away her vacuum cleaner). There seems to be something fucked up going on with Marmaduke's eye.
