Celeste drops first Misty, then Shawn into her maw, her tongue playing around a little with each of them before she swallows. Once they reach her stomach, it will be obvious that they have been shrunk, as the sphincter behind them is now as large as a house. There are hundreds of items dotted around, and those that can't be allowed to get wet are kept in chests dotted around. The items have all been shrunk too, to make room for them all. There are fewer and fewer items the further back into her stomach they look, and the very end is completely bare, dipping down to form a large pool of acid where she presumably sends any food that she intends to digest.
