When Dipper cant sleep at night, or needs comfort, or just if Bill's in a good mood, Bill will sing to Dipper. He prefers to sing creepier songs with darker lyrics, his three favorite songs to sing to him are Bernadette by IAMX, I Know I'm a Wolf by Young Heretics, and Horror of Out Love by Ludo, each depending on his mood. He's actually quite good. Dipper finds it adorable.
