Those are very nice, particularly the Berry plush.
In fact, I do like them just that little bit more than the more famous line of official plushes. I liked them enough to invest in one (Wilt), but I can't say that I was ever overly wild about their designs. There's just something about them that's always seemed slightly off. I find the facial expressions on this particular range to be a bit cuter and more appealling.
A shame that the Foster's characters were never properly picked up by a plush-making company - given the immense diversity of unique and colourful characters within the show, I think they could have milked quite an impressive little collection from them.
