I want to know the answer to the following question:
What special item is included with certain versions of Twilight Princess HD?
All the background I'm provided with is that "Special bundles of the game contain a Wolf Link Amiibo figurine, which unlocks a Wii U-exclusive dungeon called the "Cave of Shadows" and can carry data over to the upcoming 2016 Zelda game.". Is that enough to answer the question?
Answer: yes
