Either jump on it or throw something at it.
You hit the block that the shoe goomba is on.
defeat it with bombs
Run fast and defeat al of the mini goombas following King Goomba. After you defeat the first of them, more goombas will appear. Keep doing this and then finally King Goomba will run out of mini goombas! Then he will give up and give you a power star! And then you get another star! Good luck!
The castle boss is a very large goomba that can only be damaged with ground pound attacks
I assume this from Super Mario DS. If so, as Yoshi, run around the stump while King Goomba is chasing you. Behind him are a couple of his Goomba henchman. Swallow one and turn it into an egg. Then, get close enough behind the group and shoot. The egg should automatically home in on the Goombas and nail King Goomba in the back. Do this three times to defeat him.
