"Noo!" You scream as your struck by the tongue, and become stuck to it like glue. No matter how you struggle you only end up more stuck to the tongue. Suddenly you feel the tongue moving as he starts reeling it into his mouth. You watch as the first of your siblings reaches his mouth and it's unlike anything you've ever seen outside of your nightmares. His mouth expands and stretches to eventually fit the other Purrloin inside completely. He uses his forepaws to help stuff her in and closed his mouth around her. He waited for a moment with her squirming inside of his mouth before he tilted his head up, and blinked as he swallowed. The bulge your sister made slid down his throat with ease and traveled down his chest and settled in his belly. You could see the small bulge still moving even after it settled.
He then repeated this again with Another sibling. And then another, and another, watching his belly grow with each one. And then it was your turn. You watch him rubbing his bulging gut, bouncing up and down from his prey resisting inside. By now you were so stuck onto his tongue that you could barely move. He reels you in further until you are enclosed in his mouth. After a minute or so trapped inside you feel a sudden pull on you and down you went. Swallowed and sent to the frog's stomach. There you were tightly packed together with the others. You feel a lot of movement as the Greninja leaves the den to return to his lake. You feel something pressing from the outside as he rubs his belly and then lays on his back in some shallow water, splashing some across the bulge he's sporting.
On the inside you can clearly hear his stomach starting to gurgle. The walls begin to church over all of you and the stomach is already secreting some acid. You kick the wall in one last act of rebellion. It didn't have much effect. It was too tight of a fit inside and the frog's body kept you contained. You're now destined to be nothing more than frog food, your body nourishing and becoming part of him, and your remains simply being discarded once his body is finished with you. The whole idea angered you until you finally pass out.
And it is all exactly what happened. Over the next several hours you and the others were digested and added some pudge to the Greninja's body. Then he disposed of your remains in the woods before walking away in search of his next prey.
