The Berenstain Bears and the Green-Eyed Monster

Illustrated in full color. Sister can't believe the gift Brother gets for
his birthday--it's the biggest, shiniest three-speed bike she's ever seen! She
may not be big enough to reach the pedals, but "she wants that bike!" The
evils of jealousy become clear in a nightmare in which a green-eyed monster
convinces Sister to prove that she can ride the bike. But look out! Sister--and
the bike--are headed for trouble.
