We had those too. I also had that ball with the plastic ring around it to jump with. I had a KITT with 4x4 wheels and the stick shift on top of it as well.
My brother had a Back To The Future skateboard
Have not thought about that rocket in Years! We also had one that was about 3 feet tall, that you hooked the base to a water hose. After launch, the base spewed water until you turned the faucet off. Neighbor's bull dog attacked the spewing water and bit the launch base. Never worked again!
