At Treasures! Island, young explorers are sure to have a blast in a vibrant fantasy world where they either slide down can climb on, into, and over everything in sight! Located on the second floor of our Oasis building, this fun-filled romper room ensures adventure and excitement at every visit with its netted passageways and tubes for scooting and climbing, giant hollow "tree", and slides where little ones can swoop down into piles of colorful balls. Shhh, it's a surprise: Penton the penguin even stops by to play in the island sometimes!
