Nanosaur Hints

Red egg-(stegasaurous) It is in multiple places- the easiest is in the center of the lake
Blue egg- (Triceritops)The fourth island in the lava area
Purple egg- (annoying green guy) Just walk into the place with the rocks and soon you will see it (careful, it looks blue!)
Green egg- (Pterodactyl) Keep going straight through the rock area and then you will see a cliff. Use your jet fuel to get up there.(if it runs out, hop on a pterodactyl!)
Orangish yellow egg- (T Rex)Next to the cliffs with the Green eggs
