All the sounds a talented mockingbird can utter are depicted in bright gold from the ""Poof, Chugga, Toot"" of an ocean liner to the ""Plunk"" of a pin. Interesting, but impractical? Hardly -- for young viewers will surely guess the identity of the fierce giant whose roar sends two menacing hunters scurrying from the forest. Murray Tinkelman's lavish designs are admirable, though somewhat confusing for very young children to ""see"" in their entirety. Their luxuriance contrasted with the one-line low-keyed text will kindle a definite response (be it positive or negative) in most readers.
