I heard something like it called crocodile moray. I don't know how to spell it exactly but it goes a little like this:

Crocadile moray,
croc, croc, croc!
Ey cinco cino,
Cinco, cinco,
Soc, Soc,
Ey cinco cino
Malo, Malo,
malo malo malo!
Uno, dos, tres, quattro, cinco!!!

Yeah, my spanish (?) is a little rusty, but you get it. Sound familiar to anybody?
