It was in the area where you need to get the 'badankadonks' for Tiny Tina. I pushed it and is said something like "found 1 of 3 switches to summon something" but I was being attacked by Buzzards and couldn't pay attention.
Does anyone know what that was and what it did? Where are the others?
If you don't like Giantbomb then I don't like you, isn't that right Zach?
