Amusing

Isn't it one of the seagulls from Finding Nemo ?

Nice Joke

Animation was good, and it was funny. I'm guessing that was your primary goal, so I have to say that you achieved it.

you forgot to stop noises in the AS

that was really simple and funny :D
but the sound didn't stop with the movie and when replayed the sounds overlapped eachother. this is fixed with a piece of coding in the AS, checkout the flash forums or look at some of the tutorials.
good stuff!

lol

its funny how to see the birds fall in to the water
