Awesome!
This was one of those "WTF?!" kinda Flashes...I like it! Definitely original! Also, you're a fantastic artist!
If I may, I have a couple of suggestions for sequels:
1. Follow the birds' lives and see how they interact with all sorts of things they see during their travels.
or...
2. Focus on the manetee, and have multiple creatures come and go, and see what their reactions are to the manetee's bizarre...behaviour...(or whatever the hell he was doing).
You don't have to use either, but it's just a suggestion.
Keep up the great work!
