Ruffnut's Lullaby is a song that Ruffnut sings to Scauldy in Free Scauldy.
Lyrics
Ruffnut: Hush little Viking, don't you cry, or the Berserker will stab you in the eye. Don't let the enemy see you afraid, or he's gonna gut you with a rusty blade. If that dragon hears your moans, he's gonna mash up all your bones. (Scauldy Snorts) Uh . . . Sorry. I promise Scauldy if you don't kill me, my friends and I will get you out to sea. [A few minutes later . . .] Hurry up guys and fix that wing, because I've run out of things to sing!
