That gold castle was most likely either jiggywiggy's or jing-a-lings. Giant's Lair wasn't really a world. More like a test map. Though, if you want to see something cool with the Giant's Lair, well, give me a few months on that.
Actually, I think if you look carefully, you can see one of those hologram things in an earlier part of the movie, and it looks like a jinjo or something.
