Animated short film - what is it called?!

Ok, I've seen this little animated short film a couple of times now. It's not like a Dreamworks film where they show it right before the movie (or right after), they were showing it during the 15-20 minutes before the previews even started. (Like when Regal Cinemas does their "20".) This was actually at Rave Motion Pictures where I saw it. Anyway, it shows a walrus singing to a crab "If you were a slimy rock, I'd be your little barnacle." He's playing a ukele and there are little oysters as his back-up singers. Then it turns to the crab and he goes "ah ah" and jumps in the water. If anyone can tell me what it's called or where I could find it, I would be forever grateful. I've been searching google and youtube for months! ut:

Well, after ALL that searching I actually found it myself. Gee, as soon as you finally give up and ask for help, you find it. Gah! For anyone who wants to see it....clicky!
