Nintendo sent out a press release this morning detailing how Amiibo will work with the upcoming Zelda: Twilight Princess HD for Wii U. In short: Wolf Link will unlock a challenge dungeon; Zelda/Sheik will heal you; and Ganondorf will—hilariously—double the damage you receive from enemies.
When Zelda meets The IT Crowd. This fun crossover wallpaper/shirt design, titled "The Legend of Jen," was posted to r/zelda by the artist himself, Ryan Astle. You can find more of his artwork over at his Tumblr, and at clothing sites like RIPT.
