Cobblestone Minion

Cobblestone Minions are a type of Minion that collects Cobblestone. When the player begins SkyBlock, there will be one near Jerry.

Description
Cobblestone Minions are unlocked at and can be placed on the Player's Island. They are the first kind of minion the player encounters.

The Cobblestone Minion collects Cobblestone. Cobblestone minions can be made approximately twice as fast by building a cobblestone generator next to it and covering every other block with something other than cobblestone. This will make it so the minion will skip the placing action completely. However, this doesn't work when the player's island is inactive.

Strategies
If you make a Cobblestone Generator for the Cobblestone Minions, it will double their speed, so the profit will be doubled but the action cooldown will not be halved. This strategy is only effective when a player is on the island.
