There is a link to his picture.
Sundy here on the planet also has a flushmate & there is another one, but I can't remember where he's at off the top of my head right now, but if I remember right he may have a shorter tail.

There is the link to the 4th flushmate. It slowly came back to me. Sinclair's own the 4th one, Discovery, and they sold packages on him.
