Imagine that goblins can’t whistle. Besides speaking, they only know how to howl, snarl, growl, grunt, etc. But they don’t know that fairies and elves CAN!
What if Marianne discovers this and trolls Bog by randomly whistling when he’s not looking?
Bog: *whirling around for the thousandth time* “What the bloody hell IS that?!”
Marianne: “Gosh, I don’t know, Bog. Must be a bird.”
Bog: “BIRDS DORN’T SING BOHEMIAN RHAPSODY!”
