Oh the hue manatee!
Adam Rifkin stashed this in gifs
I was first introduced to Hue Manatee in Lucas' puntastic animals collection: http://pandawhale.com/convo/1731/puntastic-animal-pictures
But that one was a static image.
Little did I know there was an animated gif!
I might need to start a Manatees stash... Oh, the humanity!
