[Stone can't talk in this form, but he does arrow up towards the object or whatever it is, using his wings now to propel him now. He clings to the object with one hind foot, the leading edge of one wing, and his tail, and reaches up to pry at the hatch with a couple claws. He's too close to really see where any latches or locks are, but his claws might catch on one. Either of the humans might have better luck, if they want to swim up, or climb up the offered free hand to investigate more closely.]
