Trying to remember this old toy from late 80's to early 90's?

I remember these little plastic toy animals that as far as I know only were cats and dogs. They had roundish heads and small bodies, but had hair you could brush. The first one I had I think was a dog. It had floppy 'hair' ears on either side. It was white and I think on it's side was a blue ice cream cone. The other one I had was a cat. It was mint green with white hair. This one was a nail polish one. You could use hot or cold water to make the nail polish appear/disappear. I'm thinking their name had something to do with ice cream. If you know what these are, help?
