Giddyup 'n Go

Giddyup 'n Go is an unmarked quest in Fallout 4.

Synopsis
Arlen Glass wants help rebuilding a Giddyup Buttercup so he asks you where to find the parts.

Walkthrough
Speak to Arlen Glass in The Slog and he will ask you to find the Giddyup Buttercup toy parts to fix up a Giddyup Buttercup toy he is working on. There are two options to do this:

Option 1
Head to the Wilson Atomatoys factory and kill the Super Mutants there. Loot the key off the Super Mutant Master and open the locked door and grab the parts. Take them back to Arlen Glass and he will reward you.

Option 2
Pass a speech check telling Arlen Glass where the parts are. He will head there himself and get them. He will leave a Giddyup Buttercup where his terminal was shortly after doing this and will disappear from the map.
