Water the fire pit. After watering for sometime will be able to pick the gem that's the
first door key.

To get the other key (pink), u need to make a potion. Notice that pink diamond thingy on
the cliff? thats it. Since its too high, u need a light n springy potion. use 1 rose and 2
black orchids then have one of your villagers drink it, then drag your villager below the
pink key and s/he'll get it. haven't logged in for a while...
happy to help :)

the potion for the light and springy potion is a cacti a rose and a lotus flower
