Bubbles is a fish with a big heart and huge imagination who dreams of ponies and clouds and magic. When it looks like all hope is lost in retrieving the blue medal on the journey for our treasure, it's Bubbles and her vivid imagination that saves the day. She's Tank's buddy, and a big sister to Dorsel, whose paranoia and worrying Bubbles finds charming. Bubbles is the charm and beauty of our fish trio.
