Where Can I Find A Couple Red Fangs?

[arylonthedancer]

I found my way back to the Ragnarok. Those Chocobos are tricky little punks! Now I want to upgrade my weapon to the Twin Lance. I have everything I need except for two Red Fangs. I assume there is a certain enemy that drops Red Fangs. If anyone knows what enemy it is, and where I might be able to find it, I would really appreciate such knowledge.

I'm fairly certain the Hexadragons and the Blue Dragons drop them on the Island Closest to Hell. Maybe even the T-Rexaurs.
