Town-In-A-Box

The box.

The Town-In-A-Box is a device that deploys a town wherever it is desired. It was invented by Hobart Grapplehammer, a goblin genius behind many products for the Kajaro Trading Company.

Types

There are different types of Town-In-A-Box such as:

Town-In-A-Box - Deploys a town that can contain some houses, a poultryizer (for food), a forge, an anvil, a mailbox, a KTC Train-a-Tron Deluxe, a goblin barbecue, a "micro" mechachicken (also for food), and seemingly a generator for power, along with a control panel in the center of town. It can also contain docks and an oil refinery.
City-In-A-Box - The same as a Town-In-A-Box but in a larger scale and with more buildings.
Airbase-In-A-Box - Deploys an airbase. It is advised not to deploy them on mountain peaks.
Lab-In-A-Box - Deploys a lab.

It seems that goblins can hide inside the boxes as Hobart Grapplehammer and Assistant Greely were inside of the town that was deployed in the Lost Isles.
It is interesting to note that the boxes containing the town shake like there wasn't enough room for the town before it opens.
The concept of the Town-In-A-Box might have been inspired by the Tiny Great Hall, Tiny Castle and Tiny Barracks of Warcraft III.
Goblin technology allowing to put a whole town in a little box might be a reference to the Fallout franchise, especially to the Garden of Eden Creation Kit.
