Last part of one of my favorite Pokemon episodes <_<;
I suggest you watch the other two parts too, the second part is where I started tearing up a slight bit, where Ash finds Chikorita in the snow and she starts (for lack of a better word) snuggling Ash. And the whole last part is really sweet, but I guess that's because she actually kissed Ash... I'unno.
Chikorita is by far my favorite pokemon by the way.
