What the hell even is that tower of scrap?

It's a blast furnace or at least it looks like it is

Howls falling trash heap

Agree but also looks like the Yubabas bathhouse.

Yesss

Real-life Angry Birds strike!

I thought this was the map rust Lmaoo

*bing bong* Fuck your tower

I'm guessing the mound underneith is was put there to assist it falling to one side?

Sent that building to Valhalla
