This was a cute little animation that tells the story of a sperm.
I liked the part when timmy gave up at everything by using a jack hammer and dynamite. Then he gave up and sat down on the egg and fell through it. Music was good too.
Not bad, but your animation needs some work, and like YoungMelo159 said - the baby winking was kinda creepy looking. Regardless - good job.
the bit at the end with the motion tweening and the little fella winkign at me freaked me out.
