The boat floats and can be equipped with the included underwater motor. One figure can stand at the controls and hold the wheel and throttle at the same time. A transparent bottom with magnifier function can be found in the middle of the boat. This enlarges the underwater world to make it easier to see. The mussels, eel and starfish are flat enough to place them on land and look at them under the magnifying glass as part of play. All the included animals float on the surface of the water during play; they therefore CANNOT be observed underwater. The two underwater motors can be swivelled up and down.
