Something's Fishy

The fourth grade is studying fish, and that means a trip to the Cherrydale Aquarium! Everything is going along just swimmingly until Ms. Sweet drops her brand-new engagement ring into the tank-and Katie turns into a fish! Now she's stuck in a tank and she's all wet. Well, at least she can try to find Ms. Sweet's ring ... although that may be difficult when Katie the clown fish is being chased by a shark!
