I remember collecting these when I was younger, but I don't know much about them. There are a few I would still be interested in collecting, but I can't seem to find much on them. I did a little research sometime last year, and unless I'm mistaken, thought they might have been part of or possibly an offshoot of the IMP line. I now cannot find the site that I found that information on. If anybody knows more about these, or have any I'm looking for for sale I'd like to know! I will, however, need to dig mine out and find a complete list of the produced animals to know which ones I need.
These animals came in a plastic packet which contained a random animal, a family album, stickers of the included animal and a candy bottle. Here are some pictures of the packaging to help those memories bubble up to the surface:

EDIT I'm pretty sure I found the site I had done some of my original research on
