I was walking around and hit an item block, and something that looked like garlic popped out. I grabbed it, hoping it wouldn't kill me. Good news is that I am not dead, but now my hat has horns coming out of it. What did I just do? Is this a good state to be in? How does it help me?
The bull horn hat provides three abilities. The first is an improved version of your charge attack which can break blocks in one hit instead of two. The second is a groundslam which stuns enemies. This is executed by pressing down while jumping. The third ability is to stick to ceilings by pressing up while jumping. It is a good state to be in.
