That's an unusual spelling. I know of a flower called the Celandine which is pronounced the same as this character's name. I wouldn't be surprised if that's where Funnyseawave got it from...

And in Martin the Warrior, there's a snooty sexpot of a squirrelmaid named Celandine. She's part of the Rambling Rosehip Players. I had a HUGE crush on her after reading about her. Funny, I know she'd probably be repulsed by my eccentric behaviour, but I still wanted her...

Heh, at first, when I saw the thumbnail, I thought it was Celandine the squirrel turning into a weasel! That would have been a Kodak moment!

Thank you for a such complete comments, they really made me glad. It's the Redwallish fanart (I drew a lot of requests), 'cose I spent much time on Russian RPG and Redwall-related forum, it's a time of vermins now, so my friend has a weasel character with name of BD's character from the book. =)
I like first 9 books of series, but other are too similar. :( Did you read Welkin Weasels by Harry Kilworth?
