Or or or lol you could always get a super black pastel het pied and breed it to a piebald??? It might be a tad more on the less expensive side but its still gonna be costly. If not then IMO if money is no issues id get a proven breeding pair of panda pieds. And I agree they are amazing looking snakes.
This still wouldnt get you the panda pied I'm pretty sure. Someone feel free to correct me. At best you would still only get black pastel pieds.
