They are still called Grizzly bears as it is always a Male polar bear mating with female grizzly bear. As the female brings up the offspring it is only taught grizzly bear ways.
but the father could still teach him to hunt seals in the artic & how to survive sub zero temperatures if they share custody, spring, summer autumn with mum & winter with dad since mum will hibernate, a child of both cultures.
Depends on how you wanna kill 'em...
ex wife please & please feel free to take as long as you want & make it as painful as possible, I will supply copies of the credit card bills that I had to continue paying for years that you can show her, just so she knows who sent you.
photographic evidence will be needed as proof upon completion to receive payment. A bonus will be paid for an additional photo of the look on her face after she sees the bills and realises I sent you.
payment will be in small unmarked bills left behind your local McDonalds restaurant.
