Always up to something

I think I can fit into this basket

 No matter what is on the floor Walker is there checking it out.  This is the basket I keep spuds and onions in on the kitchen floor.  I was bound and determined that I wasn't going to move things around and keep Walker from getting into them.  This day he tried and tried to take something out and then decided to just get in the dang basket.

I thought I could get into it.   Sure enough he made it but he didn't stay in there very long.
