N in-game guide to find heart pieces

Yes. The only way to get the piece of heart in The Lumpy Pumpkin is to knock down the chandelier. There aren't any items that will retrieve it for you. I'm pretty sure you're supposed to knock it down, so you can work to pay off your debt:

You get a piece of heart when the owner is through with you.

There are 20

This includes:

• 6 that you start with
• 6 from the Pieces of Heart (there are 24, and you need 4 to make a full heart container)
• 2 from the Life Medals
• 6 from the bosses in the game. (Demon Lord Ghirahim, Pyroclastic Fiend Scaldera, Thousand-Year Arachnid Moldarach, Ancient Automaton Koloktos, Abysmal Leviathan Tentalus, and the second fight with Demon Lord Ghirahim all reward you with a heart container after you defeat them.)
