What were those tiny toys, similar to Crazy Bones?

They looked a lot like these: http://www.madhattersneverland.com/Blogi鈥?/a>



But i think they are much older, because i played with them as a kid in like 2001 - 2006.

They all had different numbers on the back or bottom like these. I remember that number 1 was a long headed slimy thing, showing his tongue. EVERYONE here in europe played with them! the entire school, would be invaded by kids playing with them! it was insane, and it was my childhood! I would really like to know what they are called again!What were those tiny toys, similar to Crazy Bones?
