It's an Arcanine, the Fire Pokemon. Its reddish fur and black stripes on it body look like ember under the sunlight. The dog-like creature looks at you with curiously with its dark eyes. The giant Arcanine is more than 200 ft tall.
"Hmm...this thing smells like a human but how does it get so small?", Arcanine exclaimed.
"Hey........", you screamed, trying to get its attention. You saw the Pokemon raised it ears a little, apparently hearing your faint call.
"So, you really are a human, but why is it that you're so small? You wouldn't last long out here.", the Arcanine asked you.
"I don't know what happened. I somehow got shrunk walking alone in this forest. For now, I don't know what I can do about my problem.", you said.
The Arcanine looked at you for some time before speaking again: "I can understand your feeling. But then again, you're highly unsafe out here. But don't worry I got an idea. Why don't you live in my body for the time being until we can find out the source to your problem. My body can sustain you with food, water, shelter, and any thing you need."
"That's preposterous!", you exclaimed, "Am I not going to be digested just by entering your stomach, let alone live in your body?"
The Arcanine suddenly give you a little smirk: "You don't have to worry about it. My acids won't affect you because I can control almost everything in my body, so I can "tell" my body to recognize you as a guest, not some food. So you can just allow me to do the rest for you."
The Arcanine opened its mouth and signal for you to enter it. Despite being a little scared about being swallowed down,the Arcanine is right, you wouldn't live long this size alone. Well, you thought, it's better to be with this seemingly nice Arcanine than to venture on in your current form in this mysterious forest. You enter the mouth and you immediately feel the soft tongue beneath you moving. You have a clear view of the Arcanine's rows of sharp teeth glistening with saliva. Moving farther, you come toward the huge gullet where you take a deep plunge into Arcanine. The esophagus is constantly pulsating and moving you toward the stomach.
After traveling for an unknown time, you arrived at the Pokemon's stomach. The stomach is quite huge, the equivalent of huge lobby. There's no acid in the stomach confirming that Arcanine's statement that he won't hurt you. What makes you realize that this Arcanine isn't some ordinary one is the fact that its stomach have more than two holes; you roughly estimate that there are at least 6 holes in here, where could they lead to.
You're thinking about asking the Arcanine or going on alone?
