Sheltie Goes to School — Peter Clover

Sheltie the little pony with a big heart! Emma's school is holding a fair, and Sheltie is going to give the children rides around the playing field. When he gets very interested in the janitor's storage shed, he is ordered to keep away. But Sheltie can hear noises coming from inside, and he won't stop until he finds out what -- or who -- it is.
