Battery Powered Lollipops (Chupa Chups?)

[Morton]

Who remember these lollipops. It was like a plastic base you could hold, with a head on top (I remember street sharks and a Frankenstein one) and there was a button on the base. When you pressed it, the mouth would open and the lollipop would pop out of the mouth. It was run by batteries I believe although I'm not sure. They came in different characters.

Anyone know what they were? they used to sell them in woolworths, and they're not Pez.
