The team that delivered the winning and funny Sheep in a Jeep have joined forces again for another irresistible trip in rhyme. The sheep are depicted as pirates, lulled to sleep on a calm green sea, but are awakened as Dark clouds form / a sudden storm.'' The boat pitches asWinds whip. / Sails rip. / Sheep can't sail / their sagging ship.'' Sheep abandon ship for a raft, dragging their treasure chest along, and drift until Land ho! / Not far to go.'' When the dripping sheep finally reach the dock they areglad to end their trip.'' The spare text is easily mastered by the beginning reader, while adults reading this aloud will appreciate the tongue-twisters and rollicking rhymes. Apple's softly shaded colored pencil drawings add just the right touch of whimsy. Readers will hear the call of the sea, and wish for another adventure--soon. Ages 2-5. (Mar.)
