Trog/Gameplay

Controls

 * Joystick: Use the 4-way joystick to direct Rex (or Bloop, Spike or Gwen if you are player 2, 3 or 4) around the islands; try not to fall over their edges.
 * Punch Button: Use this button to make Rex (or Bloop, Spike, or Gwen if you are player 2, 3 or 4) punch out at the Trogs; one punch shall stun them but several shall knock them off the island. If your triceratops has eaten a chilli pepper he (or she, in the case of Gwen) shall spit flames at the Trogs.
 * 1, 2, 3 or 4 Player Buttons: Push these buttons to in order to start the game as Rex (player 1), Bloop (player 2), Spike (player 3) or Gwen (player 4).

Triceratopses
These four dinosaurs are the protagonists of the game; Player 1 controls Rex (red), while Player 2 controls Bloop (blue), Player 3 controls Spike (yellow) and Player 4 controls Gwen (purple). They start each island in the top-left, top-right, bottom-left, and bottom-right corners respectively (like the four lords of Namco's Exvania would do two years later) - and they must collect all the eggs of their colour upon each island while avoiding the pursuing Trogs, but they can punch out at them to stun them, and knock them off the island if they do it enough times. They shall lose one life whenever they are caught and beaten to death by a Trog, fall off the edge of the island (or into a tar pit), get rolled over by a stone wheel or crushed by a green Trog's spring; however, they will receive an extra life every 500,000 points by default. Once a triceratops has collected all the eggs of his (or her, in the case of Gwen) colour, he (or she, in the case of Gwen) must go to the base marked "HOME" of their colour - and once all four have done so, you shall all be treated to a cutscene featuring the triceratops who was the first to finish, dancing, with either "CONGRATULATIONS!", "NICE WORK!", "GOOD JOB!" or "DINO-MITE!" above him (or her, in the case of Gwen), and if there is more than one player, the text "75,000 POINTS FOR WINNING" will appear at the bottom of the screen.
