It has three enrichment options: Soap Bubbles, Water Fountain (Delphi Gator), Ice or Gelatin Dispenser (tested in our driveway before we headed to Dolphin Research Center last week)
The underwater paddles are designed for the dolphins to press with their rostrums. The paddles have different numbers of holes to allow the dolphins to identify them using their echolocation. Paddle #1 has two holes, Paddle #2 has four. Paddle #1 must be pressed first to activate the underwater bubbler which enables Paddle #2. Paddle #2 needs to be pressed to activate the enrichment (water spray, ice/gelatin dispenser, bubble machine) (watch the video below this photo)
