The Triumphs of Fuzzy Fogtop by Anne Rose. Pictures by Tomie de Paola (Dial, $2.95. Ages 4-8). Fuzzy is a Russian peasant, and he hasn't the foggiest! In these three sketches of Fuzzy's typical foggy exploits, he loses his clothes, then himself; thinks he's traveled by train to a neighborhing town when he's only taken a nap and never left his own village and, finally, meets a stranger in the park and thinks he's an old friend. Tomie de Paola's drawings portray Fuzzy as just what he sounds like--a good-natured, roundish gent with a very fuzzy head of hair.
