A comic of two foxes, one of whom is blue, the other is green. In this one, Blue and Green are in bed. Blue is sound asleep, as Green wakes up to a prolonged, high-pitched, continuous eeee-sound. Green, thinking: Wait, what's that sound? A child screaming? Outside, this late at night?  Frowning and sleepy, Green lifts his head from his pillow and looks around, trying to determine the source of the sound. Green, still in thought: There it was again. Where is it coming from?  As he looks around, Green's gaze lands on Blue. Still groggy and sleepy, Green nonetheless looks visibly relieved. Green, still thinking: I can't decide what to do about it before I figure out wh- oh.  Green cuddles up to Blue, who is still just as serenly asleep as ever. The whistling sound continues, coming from Blue. Green, still in thought: It was just your nostril whistling.
