Islands 11 and 12[edit]
On these islands, there are forty-two eggs (for the 10th time, of each colour if you are not playing it alone, but if Bloop or Spike are present, the eggs in the top-right and bottom-left corners will again not be there, and if Rex is not present there will again be one in the top-left corner) and only Blue Trogs; however, on the twelfth island, there are Brown and Red Trogs in addition to the Blue ones, who can get rolled over by their fellow tribesmen's wheels.
Island 13[edit]
On this island, there are forty eggs (for the 11th time, of each colour, if you are not playing this alone, but if Bloop or Spike are present, the two eggs in the top-right and bottom-left corners will again not be there, and if Rex is not present there will again be one in the top-left corner) and Brown, Red and Blue Trogs; there is also a pair of red Warp Doors which will, yet again, warp the triceratopses and Trogs from one to the other when they are entered.
Island 14 (Bonus Stage)[edit]
On this island, the text "BONUS WAVE. DIAMOND MINE! GRAB THE JEWELS! (YOU HAVE 15 SECONDS)." will appear on the screen as the "HOME base opened" theme starts to be heard from the Yamaha YM-2151 and forty randomly-generated jewels appear all over the island; the Rubies are worth 500 points, while the Emeralds are worth 1000 and the Diamonds are worth 2000. If you manage to collect all forty of the jewels between you before the timer runs out, the text "ROCK ME BABY! 100,000 POINTS FOR EVERYONE." will appear on the screen (but, if you do not, the text "TIME IS UP!" will appear instead) - and if your triceratops falls into the enormous hole in the centre of the island, he (or she, in the case of Gwen) shall be eliminated from the stage. After this stage, you will be treated to the second cutscene of "Trogs' Cave", which depicts a Brown Trog carving a picture of one of his fellow tribesmen jumping over a bone onto a triceratops onto the cave wall, then imagining himself bouncing into the air (which is what the Green ones will do).
Island 15[edit]
On this island, there are thirty-nine eggs (for the 12th time, of each colour, if you are not playing this alone, but if Bloop or Spike are present, the eggs in the top-right and bottom-left corners will again not be there, and if Rex is not present there will again be one in the top-left corner) and only Green Trogs; there is also four springboards, which will propel the triceratopses from one side of the island to the other, and the Green Trogs upward into the camera.
Island 16[edit]
On this island, there are thirty-eight eggs (for the 13th time, of each colour if you are not playing this alone, but if Bloop or Spike are present, the eggs in the top-right and bottom-left corners will again not be there, and if Rex is not present there will again be one in the top-left corner) and only Green Trogs; there is also four springboards, which will propel the triceratopses from one side of the island to the other, and the Green Trogs upward into the camera.
Island 17[edit]
On this island, there are thirty-five eggs (for a 14th time, of each colour if you are not playing this alone, but if Bloop or Spike are present, the eggs in the top-right and bottom-left corners will again not be there, and if Rex isn't present there will again be one in the top-left corner), and both Brown and Green Trogs; there is also four springboards, which shall propel the triceratopses from one side of the island to the other, and the Green Trogs into the camera.
Islands 18 and 19[edit]
On these islands, there are thirty-nine eggs (for a 15th time, of each colour if you are not playing it alone but if Bloop or Spike are present, the eggs in the top-right and bottom-left corners will again not be there, and if Rex isn't present there will again be one in the top-left corner), and Brown, Red and Blue Trogs; you must remember from the twelfth island that the Brown and Red ones can be rolled over by their fellow Blue tribesmen's stone wheels.
Island 20[edit]
On this island, there are thirty-six eggs (for a 16th time, of each colour, if you are not playing it alone but if Bloop or Spike are present, the eggs in the top-right and bottom-left corners will again not be there, and if Rex isn't present, there will again be one in the top-left corner), and all four Trog types; there is also a pair of red Warp Doors, which will (for the fifth time) transport the triceratopses and Trogs from one to the other when they are entered.
