This book felt familiar as I read it, and a quick search of my LibraryThing tags for "kangaroos" and "messiness" immediately brought up Oh, Bother! Someone's Messy! by the same author and illustrator. I pulled that off the shelf and a comparison shows that Roo's Messy Room is an abridged version of the same work produced a couple years later. Sentences have been dropped, chopped in half and rearranged. Some pictures have been discarded, and large pictures have been cropped into two or three smaller pictures. And poor Eeyore was completely removed.

Since Disney recycled, I'm just going to recycle my rating and review too:

Roo's room is messy, so Kanga does the old let-him-soak-in-his-filth-till-he's-sick-of-it trick. Since this is a fantasy, Roo learns the error of his ways, and since this is a Pooh story, all the Hundred-Acre friends come over for a book-ending cleaning-up party.

I tried this with my daughter's playroom for a while, and we ended up with two-foot drifts of papers and toys against the walls and a three foot diameter circle in the middle where she could actually play.

(My Pooh Project: I love Winnie the Pooh, and so does my wife. Having a daughter gave us a chance to indoctrinate her into the cult by buying and reading her every Pooh book we came across. How many is that? I’m going to count them this year by reading and reviewing one every day and seeing which month I finally run out. Track my progress here:
