Looking for special lures...

I recently was made aware of a hard to get lure that looks like a frog. The
colouring is black with a pink belly and has long dangly flexible legs. It
is mainly used to catch yellowbelly and other freshwater fish. I'm living in
far north qld and there are plenty of great fishing spots inland up in the
Kuranda ranges and further north too. Feedback greatly appreciated.
