Your task as Chuck Junior is to complete the six different scenes (which will be split into numerous zones) and the three in between sub-games, eventually ending up rescuing Chuck from the downright horrible Brick Jagger.
Chuck Junior has a large wooden club to help him through the game. With this he can hit enemy dinosaurs, set trap dinosaurs off, bash parts of the background away and hit rocks which will move short distances. He can also set the club on fire which in turn can be used to scare dinosaurs and as a torch to illuminate dark areas of the map. Junior can also climb on top of his club so he can dodge harmful traps which cannot be destroyed.
