Go to Rainbow Mines to get the Green Gem.

After the Doctor tells you about the Green Gem, go to Rainbow Mines and follow the mine path. The puzzles are in the way of the gem, so you just need to keep going deeper until you reach the first locked area.

Ball Puzzle for Level Two Underground

The first puzzle you have to solve is in Underground Level Two. There are two balls in this room: a red ball and a blue ball. First, push the red ball. Once it's in place, go over and push the Blue Ball the same way. When you push both of them, the puzzle is solved and a bridge appears, which lets you go on.

Keep going down to the fourth level of the underground.

Go across the new bridge and follow the path deeper into Rainbow Mines. Follow the main road until you get to Underground Level Four. This is the larger puzzle room, and at first it looks more confusing because there are a lot of colored pieces.

Colored Block Puzzle for Underground Level Four

The puzzle in Underground Level Four is made up of blocks of different colors. The most important thing is to pay attention to red. Move the first Red Block into place. After that, push the next Red Block so it fits right. Next, push the last Red Block as well. When the last red piece is in place, a new bridge appears and the path is clear.

Get the Green Stone

Once the second bridge is up, nothing can stop you from getting the valuable Green Gem. Follow the open path, get the Green Gem, and take it back to the Doctor so that the recovery can continue.
