There's A Frog In My Sleeping Bag — Susan Clymer

Three whole days at camp!

Good-bye, classroom!

Good-bye, class hamster Squeaks and class tarantula Hairy:

Mr. Jenkins's third-graders are off to Camp Buffalo for three days of learning and fun. There will be
...hiking in the woods
...boating on the lake
...telling ghost stories in the cabin at night
...and, for Janna, an unexpected mystery to solve.

One of the campers is playing tricks. Who is it? And why is the trickster picking on her?
