"A simple short joke"
It was a short joke but I think you took too long to set it up.
Watching all the cute animals was kinda boring and after about the 4th I was wondering if this was going anywhere and was kind of wishing it would hurry up and get to the point.
The giraffe looked awesome when it was doing its thing but most everything else in the flash was kinda dull looking (which made the set up feel longer).
Sounds were good though.
Just speed it up (shorten the black spacing between animals) and it will be heaps better.
