Slime Key

"Slime keys are large, stone keys that are used to open the slime gates across the range. These gates often lead to expansive, new areas to explore or create shortcuts to familiar areas."

- Slimepedia

Obtaining Keys: Keys can be found after feeding the wild (not caught using a Gordo Snare) Phosphor, Honey, Rad, Boom, Quantum, Hunter, Crystal, Dervish, Mosaic, and both of the Pink Gordos a massive amount of food that their type eats (45 food items are required for the Pink Gordos, and 65 for others unless you use the respective slime's favorite food, which will halve the amount). After being fed, the gordo will burst, giving a key as well as some slimes of the same type as the Gordo Slime and crates.

Note: Neither Rock Gordo, nor either Tabby Gordo, nor the Tangle Gordo drop slime keys, but all reveal Teleporters.

Where to use them:  Slime Keys are used to open Slime Gates. Currently, only eight Slime Gates exist, leaving three of the eleven keys unused. The Slime gates are located:
 * In The Slime Sea to enter The Moss Blanket
 * In the Dry Reef to enter the Indigo Quarry
 * In the Dry Reef to enter the Beach
 * In the Moss Blanket to enter the The Ancient Ruins' entrance area
 * In the Indigo Quarry to enter the The Ancient Ruins' entrance area
 * In the Ancient Ruins to have access to the teleporter to The Glass Desert
 * In the Glass Desert, in the Rock Fountain Area to enter the second part of the desert
 * In the Glass Desert in the Pillar Area to enter the second part of the desert

Note: Even though there are eight slime gates, not all of them need to be unlocked to gain access to every area in the Far, Far, Range. Three gates can be left locked: The amount needed shrinks even further when the player has access to the jetpack, which allows the player to bypass both the Moss Blanket and the Indigo Quarry gate. With this, the amount of keys needed is actually three.
 * The Beach can be accessed via the overgrowth
 * Either, one of the gates leading to the Ancient Ruins, or the gate to the Indigo Quarry or the Moss Blanket can be left locked and the player will still have access to all three zones
 * The second part of the Glass Desert only needs one of both gates to be accessed

The remaining three keys as of the V1.0.0 release are now used to access three hidden vaults scattered around the map that are activated upon reading Cassey's final message after finding the last note left by the previous rancher at the end of the glass desert area and rolling the credits.

Vault Locations

1. On top of the rocky formations in the dry reef area gained via teleportation after feeding a Tabby Gordo Slime near the sea. The entrance is located directly above the tunnel atop the mountian.

2. Within the volcanic zone gained by feeding a Rock Gordo in the quarry.

3. Within the Jungle, after crossing the large ocean/river gap and crossing into the area full of aggresive Hunter Largos, head to the area with The boom/Hunter Largos to enter through an archway and the vault teleporter should be in view.

Vault Contents
