From the perpetrator of Lenny and Lena (1978), another ass-onant mispairing. Moose, who lives upstairs, is a noisy galoot, so Goose, living underneath, suffers. . . until her ultimatum--""Moose, you've got to move""--prompts a visiting hippo to suggest that they switch apartments. And, with more ado, they do. Lots of ruckus, with labored pen-and-ink pictures to match; but the story's strictly custard pie.
