Koopa is on YouTube.
Koopa has been featured on Product Buzz.
Koopa has his own web page.

Koopa is a turtle that paints, and his paintings hang in all 50 states, plus Canada, Bahrain, The Netherlands, The United Kingdom, Australia, and Italy. Koopa even has a MySpace page, though I don't recommend you go there under any circumstances. (As the background music says, "Gimme one reason to stay here," and I have found no reason to ever stay on any MySpace page. Hire some user interface designers, MySpace, you're not a startup anymore.)

Koopa was recently featured on Neatorama's "Caption this photo" contest, but don't bother entering, as winners have already been chosen.

I have to hand it to Koopa's human assistant, Kira, for creating this turtle/art niche. That's some genius product development right there.
