Wow! There is so much work in there. I love your sense of humor (my favorite part is when he repeatedly presses run xD).
If I had to criticize, I'd say that there are some waits that are too long (for instance at the beginning when we look at Snorlax for like 10-12 seconds) and the overall rythm is a bit too slow I would say. And that's a pure matter of taste but I think the palette of colors could be more appealing.
Some animations really show you have a great animation sense, like when the guy jumps out of the bush and also when you twist his mouth around. Overall I'd say really nice work!
