Cazet's comfy, wide-eyed, serio-comic animal cartoons give this holiday heart-wringer an engaging mien, even a degree of emotional credibility. Little rabbit Patrick misses his dead grandfather on Christmas Eve, and Mother tells him that Grandpa ""used moon magic to chase [his] sadness away."" She does a little hand-waving and finger-wriggling, then settles down with Patrick to think about Grandpa--whereupon the blues and lavenders, the spectral drawings, give way to cheery, animated-type cartoons of the various ways Grandpa helped Patrick along, made him feel big. Back in his moonlit room, ready to go to sleep, Patrick doesn't feel ""so little"" any more; on Christmas Day, he'll do for the littler rabbits what Grandpa used to do for him. Unassuming--and not ineffective.
