DanielD is a penguin in the Snowball Press in-game book Truth or Dare. He dared RodgerRodger to stay in the Boiler Room alone for a whole night, which led RodgerRodger to figure out that the Keeper of the Boiler Room was really a Green Puffle, not a penguin or any other creature. He also worked in the Boiler Room as a penguin who does cleaning and maintenance. He is a light blue penguin wearing the Black Hoodie and Red Ball Cap. It is also revealed in the book that he has the keys to the Boiler Room.
A penguin who goes by DanielD.
