UPMONSTERS for the Intellivision





The aliens from the planet UP have arrived! But nobody on Earth is panicking. Why?

The Upmonsters, as they’re called, have landed right in the middle of the Sahara Desert.

All 20 of them went to explore, but after finding absolutely nothing for miles on end, they decided to go home.

The UFO isn’t working very well in the desert heat, so the aliens need to jump on the clouds to get to the hovering UFO.

Can you help the aliens get home?



Your Upmonster can jump from cloud to cloud. Watch out for that pesky yellow bird!
