Gosh, I would help if we got to see the whole pitcher at least. Isn't it bad enough we can't really tell how big the pitcher is?
And the answer is Rafflesiana x Rafflesiana! To be more specific it's *******'s Rafflesiana (Brunei squat x (Kondo x Singapore Giant 6)). Never expected a Raff to be so toothy! Congrats Divaskid for guessing this, although I know you have one of them from Sam too ;-)
