Underwater Explorer
The only thing bad about this set was when I put my new Talking Commander (my parents failed to read the instructions to me) in a nice orange scuba suit and placed him on the underwater explorer and then into the bath tub. Needless to say, if he wasn't in a landfill somewhere, he would need to go see a Joe medic for a bad case of lost voice. Anyway, Underwater Explorer made Joe's time in the water that much better. A really cool underwater sled.
