Schmerf?!
For among your first creations when you started claymation, this is damn good.
The clay models themselves are average but the animation is quite smooth as usual. Another nice touch is that you also made "locations" instead of just clay people on a table. I'm not knocking Knox at all because that works well with his style. But it's refreshing to see something outside a table. Only thing I can criticize is sometimes you see the backgrounds shake slightly. But this was one of your very first, even before Become (which shows how much you improved), so I'll let that slide.
The humor is definitely where this one shines. Some real quotable moments such as...
"Before I hit puberty... and grew... a face."
And let's not forget the noise made by the little pink monster who seems to have some sort of relation to Jigglypuff.
Also, some of the humor was just random or well timed. One particular moment that sticks out is when the penguins attack, Peter retaliates back, but then the Charizard card of ALL things attacks him. It was so unexpected, head scratching, but goddamn funny.
The only point where the humor lagged was near the ending segment in Japan because it seemed too bland until the fight sequence. Funny thing though, Pete looks kind of like a demented Alien Homind when he grows a face while kicking ass. XD
The audio was average. Sometimes you could hear clearly, other times it was not audible.
Overall, it was very entertaining. For one of your very first claymations, it is very memorable which is always a good thing. Cheers! :)
