yarr you have to capture a goast u have to buy a inventing table
and be really good at it. I think u have to have 9 or 8 skill bar things.
when you unlock a goats zapper u have to go on the map at night
And if you see a house with a purple goast symbol go there with the goast zapper.
when u go there you might see a toast which looks like a sim and you can capture them.
or u might see another goats that is colourful and smaller.
If u capture 24 goasts on one lot then u will unlock it.
hope that helped
