Joe called to his sheep and they came running. He led them home and they got back to the shelter just as the heavens opened.

"Thank goodness we made it in time" said Joe to Bob, and he counted his sheep carefully, the same as he did every night.

"... 97 Bella... 98 Trixie...99 Suzie... 100... 100..." But there was no 100 "Oh no! Someone's missing."

Joe looked around the shelter.

"Its Sally! she's still out there!"
