Narwhals paint on walls-don't they?With its long twisted horn (actually a canine tooth), this member of the whale family is not very familiar to most children. The bespectacled kid narrator who has just created an enormous mess declares that "a narwhal is a rainbow-painting, elephant-sized, purple polka-dotted, flying pie maker" in an attempt to shift responsibility for the havoc on to the bluish mammal with the flippers and the horn who just happens to be in the house. Well, the narwhal begs to differ. How does the kid know about narwhals? The narwhal manages to convince the kid that it is the real deal, a fact confirmed by a check on the kid's smartphone. Conceding, the narrator starts cleaning up the mess, but the action doesn't stop there. When the narwhal plays a sneaky trick, is the kid fooled? The usual happy ending for a silly picture book takes place, and the kid and the narwhal end up becoming friends. Different typefaces are used for the two characters' speech (there is no narrative text); the scratchy cartoon pictures are amusing and full of action; and the introduction of a rare mammal makes for a somewhat original twist on the silly picture book. Unfortunately, the setup is too over-the-top to sustain engagement with what is in the end a fairly thin gag stretched out over many pages. The kid has peachy skin and long, straight, black hair.
