this one has a pea green and neon yellow tag but it is not truffles as she still has a pup and the colors, while similar or different.
The one below it red and pink and I have not seen her before either. Neither of these looks pregnant. You can not tell it from the red/pink's picture because you can not see the nose, but she looks to have been recently bred. Her nose is a mess of pink.
This is the second day in a row I have seen the red/pink otter but she does not seem to like to be too close to the jetty and it is hard to get good pictures of her.
