In Shovel Knight: King of Cards, when you encounter Mr. Hat at his Fancy Shop, he offers to sell you items that cost 100,000 gold each. If you leave without buying anything, Mr. Hat will follow King Knight, repeatedly ask you to buy something, then challenge you to a fight when you try to leave. After you defeat him, he will move his shop and discount his items.
What happens if you save up enough gold and buy an item from Mr. Hat at full price? Does he still fight you?
