[ID: A Gravity Falls comic drawn very on-model to the show. Young Soos, kneeling with Mystery Shack, looks up and asks, “What happened on that birthday?” Stan says seriously, “The worst possible thing…” He puts a hand on a wide-eyed Soos’s shoulder and reveals, “…I only got one cake!”
Soos squints at him disbelievingly, then bats a smiling Stan away with amusement and exclaims, “That’s silly! What’s the real reason?” Stan grins and laughs. “What?” He settles beside Soos, who’s now smiling, and says, “That’s definitely the reason.”
His next narration continues through layers of dirt and rock below the floor. “Imagine… getting two cakes your whole life…” Finally, the earth gives way to Ford’s extremely dim underground lab and the broken portal. “…only to suddenly end up with one.” End ID]
