Twilight Princess HD's Wolf Link Amiibo dungeon is basically the Cave of Ordeals
Twilight Princess HD isn't going to withhold a whole new dungeon if you choose not to pick up the Wolf Amiibo.
There's been a lot of talk about The Legend of Zelda: Twilight Princess HD this week, after a Famitsu report confirmed that the Wolf Amiibo does indeed unlock content in the game.
This content was described as a whole new dungeon, but it looks like that might have been a bit of enthusiasm on Famitsu's part combined with the filter of translation. A new trailer posted by Nintendo Germany detailing the extra goodies suggests the new dungeon is very, very similar, if not identical to, the Cave of Ordeals - a 50-floor dungeon that exists in the original version of Twilight Princess
The main difference seems to be that you're forced to play as Wolf Link at all times. This "new" challenge is called Cave of Shadows, and you can save your high scores to the Amiibo itself.
The Link, Toon Link, Ganondorf, Zelda and Sheik goodies are detailed, too.
The Legend of Zelda: Twilight Princess HD hits Wii U on March 4.
