None of the amazing creatures at the Mystic Aquarium lives in a pineapple, but most live under the sea. I've also witnessed some nautical nonsense from some of them, especially the adorable and amazingly intelligent sea lions at the sea lion show. Other treats are touching a cownose ray in the ray pool, promoted as being for kids but also for us kids at heart. The aquarium is full of mysterious and beautiful underwater creatures, including sharks and things that are absorbant and porous. Other thrills include a beluga whale and several penguins. Go see it for yourself. Many libraries have discount passes (not valid June-August).
