You would get a clutch of normals het pied. I am not too sure of the percentage. If you had a 100% het pied then the babies would be 50% het but since you only have a 66% het pied, the percentage would be lower (33%) <- even though no one uses this low of a het chance simply because it is so low that it is almost not worth advertising it.
Wrong. 66% het means there is a 66% chance the snake is het and a 33% chance it is normal. 66% het is one of the results of a het to het pairing. If it proves out to be het, you would get 50% het pied and 50% normals on average. If it is normal, then 100% normal.
