When the junk tumbles out of the closet, a tire lands around Barney's head that has some writing or marks on it. However, in the next closer shot, the marks or writing has disappeared.
When the squirrel takes the nutcracker under the bed to crack the nut, there are nuts, pieces of hulls, and the bowl that Barney used to hold them all strewn around on the floor. After cracking the nut, Barney bounces on the bed, but all the nuts and the bowl are gone. After the squirrel gets out of the bedspring, all the nuts and the bowl are back.
