In celebration of the game's second anniversary, Undertale creator Toby Fox threw out a tweet showing some new items that he's been working on related to the game. As you can see below, iMessage will be getting stickers related to the game featuring some of the more loveable characters from the game including Sans, Papyrus, and Undyne. There's also an Undertale alarm clock in the works for iOS and Android phones, and the PS4 dynamic theme is available for purchase for just $3. It's a really good time to be a fan of the retro RPG.
