The audio balance may not be quite right, but this brief and busy e-version of a nearly wordless German tree-book brings the noise.
Berated by, maybe, an older sister for heedlessly dropping a banana peel on the sidewalk, young Hubert gleefully envisions an escalating cascade of mishaps that begins with one passerby slipping. It ends—just nine screens later—in a broad cartoon streetscape jammed with crashed vehicles, escaped pigs and zoo animals, innocent bystanders splattered with food and all manner of slapstick byplay. There is no animation, but successive manually advanced scenes fade in or out cinematically and can be spread for scrolling close-up views of the action. Each scene features several touch-activated oinks, beeps, squeals and electronic sounds that are hard to hear over the overloud, percussive musical track. This is turned off in the final scene, where the sounds continue running once tapped so that viewers can create a mighty satisfying cacophony of their own.
An entertaining ruckus, still in need of a tweak or two to reach its full, parental-insanity–inducing apotheosis. (iPad storybook app. 4-6)
