Tacky the Penguin wears loud shirts and sings horribly, a contrast to the perfect, preened members of his flock (who've got names like "Neatly" and "Perfect"). But when hunters come seeking pretty penguins, it's Tacky's lack of… well… tact that saves the day. The iPad-app version of the 1990 book doesn't work much to improve upon the hilarious first adventure of the "odd bird," but the developer's trademark less-is-more approach enhances what's there without overdoing things with needless features. Animated snow is ever-present, falling slowly on every page. Background music blends gracefully with sound effects (the penguin singing is particularly well done). And the narration is lively enough to match the sharp text and expressive illustrations. Like many of the apps developed by Oceanhouse Media, every object and word on the page is read out loud when touched, and page flipping is done with simple swipes. As Tacky is prone to do to his penguin friends, the developers deserve a "hearty slap on the back and a loud 'What's happening?' " Charming and oh-so-neatly put together. (iPad storybook app. 3-9)
