Yarlett renders Poppy as an irrepressible and irresistible ball of energy. There’s little difficulty believing she’d conjure up a ghost octopus (or "ghostopus") given half the chance. The art, akin to that of Oliver Jeffers, is filled with tiny details that also add to the fun, and the creatures’ dialogue, spoken in bubbles, will elicit chuckles. Moral of the story: an excess of imagination may get you into trouble, but it’s clearly worth it.
Yarlett’s mixed-media illustrations are bold, bright, and colorful and give joyous life to Poppy’s infectious enthusiasm and creativity. Poppy’s imagined creatures are a whimsical delight, and many spreads are punctuated with clever, quirky details that reward readers who carefully examine the art…This entertaining and eye-catching story should find a place in most collections. It is sure to be a hit in storytime.
