Hatches are places where the player can find a safe haven, situated beneath Wellington Wells. For every island on Wellington Wells there is a Hatch. When the player reaches a Hatch, there is usually a locker which holds many useful supplies that will aid them. Some hatches are marked with a "Wellington Underground" sign.
Each Hatch also contains the player's Pneumatic Stash. This is used to hold the player's inventory items that they want to save, but would prefer not to carry with them. Players are able to craft items from ingredients placed in the Stash.
All Hatches are connected by underground tunnels. Players can activate Track Access Hatches to travel from hatch to hatch without any disturbance.
