Slime Rancher

Firstly, you will need to have burst a Gordo Slime in order to get a key. There are helpful solutions on how to do that here:

Once you have done this, you will now have a key. Next follow this video to get to the door to the Moss Blanket:

Once you get to the door, use the key on it and the achievement should unlock. Hope this helps!

Also, this achievement will also unlock if you haven't opened up a Slime Gate yet:

To unlock this achievement, you will need to have burst a Gordo Slime and gotten a key.

Doing the above should net you the achievement below if that is your first Gordo Slime burst,


After getting the key, head back to your ranch and stand facing the exit to the main area.

Head north out of the area, take the northern slope up and continue on. In this area, you'll see a giant rock formation that is not part of the wall. Head behind the rock formation and continue on the path. Go down the slope and when you come to an intersection with a hole in the wall to the right and a path leading to purple grass on the left, head left. Continue and head up to upwards slope to your left. Head through the tunnel and go through the opening in the rock wall ahead. Head down the platform, go around the rock area in the middle and head right through the opening in wall to a bridge. Go over the bridge and get to the next area.

Be warned. There are feral Pink Phosphor Largo Slimes here. They will attack you similarly to the Tarr. Except you can tame them. Feed them food they like, so in this instance any type of fruit: Pogofruit, Cuberry, Mint Mango, Phase Lemon, or Prickle Pear. They will become tame and you can pass through without a problem.

Though if you like, you can just run.

Follow the path until you get to a bridge. Continue along the bridge and when you can turn left onto another bridge, do so.

Here you will see a large door with a keyhole. This is the entrance to the Moss Blanket. Use your key that you got from a Gordo by hitting when in front of the door.

Your achievement will pop and if this is the first time you have used a key to unlock an area, so will this other achievement:

Hey all, quick video for unlocking this achievement. Hope it helps!

Firstly, you'll need to get a slime key by bursting a Gordo Slime.
This will unlock Jelly Belly Burst. (See my guide for this achievement)



Next, you'll need to take the route that is a straight shot forward from the ranch's exit. Eventually you'll walk across a small rock island, followed by an old wooden bridge to the slime door. If you open this slime door the achievement is yours! If this is your first slime door you'll also get the Open Says Me achievement
