"Packs in some solid jokes... Maxwell's humor is dry, and hip readers will giggle at the snapbacks and humorous dialogue sprinkled throughout. ...Cotterill's artwork...is loose and lively."
"Green slime makes a winning story ingredient, and newcomer Maxwell gives it a workout in this fairy tale whodunit. ...Cotterill's ink-and-watercolor spreads have a cheerful, retro vibe and excel in capturing the frowns and grimaces provoked by the slime epidemic. ...Fast-moving and gross enough to make a diverting readaloud."
"This fractured fairy tale is based on characters from many traditional stories that older children will be familiar with... Slapstick."—School Library Journal
