I practise south system of Hung Gar there we have a form which is called Ng Ying Kuen or Ng Yin Kuen.

Meaning 5 animal fist it includes: tiger, leopard, crane, snake and dragon. Also there seem to be a kungfu system totally focused on 5 animal kungfu called, Ng Ying Kungfu.

But also saw 3 animal styles and others. Difficult to find a true lineage i guess
