One to four players take on the role of a cute dinosaur, selected from
the four on offer: Rex (red), Bloop (blue), Spike (yellow) and Gwen
(lavender). The game takes place in a prehistoric land called "Og" and
is made up of forty-nine different islands; the dinos must collect all
of the dinosaur eggs that lay on the islands, while avoiding the unwanted
attention of a tribe of one-eyed cavemen, called "Trogs". The dinos can
punch the attacking Trogs; one punch will only stun a Trog but several
punches will knock the enemy off the screen. There are four different
Trogs who pursue the dinos:
On each island, after the dinos have gathered up all of their eggs, they must make their way to the base labeled "Home"; from here they will move on to the next island. (arcade-history)
