Three toys, abandoned in an attic trunk, make their escape--under the leadership of teddy bear Malcolm--and fetch up in the park; doll Gwendolyn is carried off by a little girl, monkey Apple is seized upon by a little boy (who, spying him in a tree, providentially names him ""Apple""), and Malcolm--after a few unexciting misadventures--plops himself on the doorstep of a woman who is ""nutty. . . about bears"": she has a whole big bed-full. One of the most routine situations around, developed slowly and unimaginatively to the totally contrived finale. (And the pictures aren't even appealing.)
