Terrarian
I was recently playing Terraria on my mobile and while exploring for sky islands I found one with a red banner/sign hanging from the bottom. There was a star shaped hole in the center of the sign. When I tried to break it I couldn't, and when I broke the block it was hanging from it just moved to the blocks above. I've never seen this before and was wondering if anyone knew what it is or what it means?
