When you are a young pixie living in the largest tree in the Magic Forest you could do with following the advice your experienced parents give you, or you'll run into trouble! But our little pixie friend Greentop is not keen on following advice, so when mum and dad go shopping, he ignores their request to stay put and goes exploring. It doesn't take long for him to be utterly lost - this is a very, very big tree indeed and it is full of secret passages and all sorts of dangerous creatures that kill by mere touch. It is the mission of the player to guide Greentop back to safety, and this is no mean task - the different areas of the tree that need exploring are devilishly complex, full of switches that need activating in order to proceed, false clues and an increasing amount of red tree-demons to avoid.
