I have everything to make the car except the gasoline. For gasoline, I need petroleum. For petroleum, I need bitumen. For bitumen, I need kerogen. For kerogen, I need fossil. For fossil, I need dinosaur. For dinosaur, I need an egg.
This guide says that an egg can be made by putting together 2 turtles. I do not have a turtle. To make a turtle, you need to put together sand and an egg.
How is this possible, and how can I get an egg to complete this madness?
