Wasted Opportunity
This was the flash that might have been. All you have is essentially the first 60 seconds of the movie, with almost NOTHING happening. The character designs were good, but there was no sound at all. No humour of any kind. No plot.
If you had bothered to put some effort into this, making it much longer and putting in some music (and voice actors) it could have been an excellent parody.
In future dont be so lazy.
