Pretty Good!
This was a very good animation, with a funny twist, What with the age changing and picoday being pico's birthday, but i think that it should be rated T instead of E.
However, it had great voice acting, smooth animation, pretty catchy music, and an adorable caterpillar being squished by some sort of demented hulk with a pacifier in his mouth. So it was pretty good.
I also want to know if the characters were original, or if I just hadn't seen them before. Keep up the good work!
