The Golden Dillo has been there for months now. I've been trying to come up with a combo for it but nothing has worked yet.
Golden Sky Dragon + Armadillo Verde
Golden Stingtail + Armadillo Verde
Golden Sky Dragon + Silver Dollar Dillo
Golden Stingtail + Silver Dollar Dillo
I have a few friends helping me because I currently am very busy irl, however the combo we are trying is the sand shark + silver dollar dillo(6 tries so far) the previous combo they were trying was (besides what you mentioned) was golden sky rattler to both verde and silver dollar dillo
Decius? are there other unknown first generation dillos hidden in game? stormy jen silver
