Thank you for pointing this out, actually I made 2 mistakes.
The pairing was Pastel Piebald x Bumblebee het Piebald. First I somehow forgot to add het in the thread name, and then when I added the picture of the male I said the female is piebald.
My apologies, the paring in question was Pastel Piebald x Bumblebee het Piebald.
