Ralph--of Bunny Trouble, 1985--thinks his baby sister, Emily, is overrated: ""She cried a lot and was always wet."" He tends to do things like poking her, not really hard, but hard enough to make Emily cry. Left to watch her, he's too busy decorating eggs (making them look like soccer balls) to notice her wander off after a passing butterfly, but her absence does elicit his concern; in fact, it's Ralph who organizes the searchers into a long line, holding paws, to comb the tall grass and eventually find his sister. Wilhelm unabashedly depicts his rabbits in a popular, expressive, cartoon-like style, but his spacious, skillfully painted settings betray the fact that his talent goes beyond caricature. Although the plot here is predictable, the telling is lively and should amuse beginning readers.
