a. That Rottie is cool. Two of our best dogs were Rottweilers. Sorry I can't help with the chip, though.
b. I found the Mohegan Sun Millennium chip on all-chips.com awhile back; check with Ricky Puskin, he might have one.
c. I have a $5 Stardancer clownfish (I think that's the fish it is) that I'm not married to; I'd trade it for a $5 of yours, if you want.
