Giddyup 'n Go

Giddyup 'n Go is a miscellaneous quest in Fallout 4.

Quick walkthrough

 * 1) Talk to Arlen Glass and accept his quest.
 * 2) Retrieve the toy parts in Wilson Atomatoys factory.
 * 3) Bring the parts back to Arlen Glass.

Detailed walkthrough
When you reach the Atomatoys building after killing the mutants, inside you will see a door that requires an ID card. To get in the room with the quest parts, get the card located upstairs over at the right of the desk in the corner on the ground. Alternatively, it may be found on the Super Mutant Overlord, or other Mutant Leader, found outside the factory.

 * Arlen Glass may be unresponsive or found dead at the Slog. Using the 'kill' and 'resurrect' console commands will allow you to complete the quest.
