A young Ruff Rogers was happily playing with his marbles (ooohey!) in his local park. When suddenly one happened to go a stray and fall down a nearby rabbit hole. Not knowing this hole was a teleport to another dimension, he reaches down to see if he can retrieve it. To his suprise, he suddenly gets sucked into the darkness.

Ruff now dazed and confused, finds himself on an alien planet which is run by Mr evil himself, Dr Destiny. He also discovers that this mad doctor controls a fearsome army of robots called the tinheads. Furthermore, he spots his marble collection is now lying scattered throughout the planet. As you can imagine, Ruff is a little displeased with his current predicament. So with this, he makes the decision to accumulate his marble collection once more and save the planet from the evil clutches of Dr Destiny and his Tinhead Army.
