Introducing...

Griffin, the dark bear from hell who goes "Gnaaah!".
Is there anybody who hasn't heard of him? He who grew to become the most famous of all bears, feared, respected and loved all over the world and in its shadows; every creature from insect to elephant knows his name: Griffin, the dark bear from hell who goes "Gnaaah!".
His story begins on a cold december morning in 1964, in hell.
Everybody knows that the dark bears have lived in hell for all eternity. Every now and then however, and although they really should know better, some of them try stupid things like revolution. Griffin's parents were of that sort. They seriously wanted to introduce democracy in hell, can you imagine? Of course that got them into trouble with Satan himself, who, on a rare notion of being humble, instead of taking their lives just banned them from hell. So Griffin's parents had to emigrate, and they emigrated to New York.
When they moved into their shabby appartment on 110th street, Griffin's father, looking at his pregnant wife, laid out the rules: "Grrr, we're still dark bears. Dark bears from hell, and nothing will ever change that!"
"Grrr!" Griffin's mother said and blinked away one single tear. Little Griffin was born the following spring, and soon it was time for him to learn the call of the dark bears. This proved to be harder than expected, because whenever Griffin's father showed his son the traditional and well respected "Grrr!", all that Griffin could accomplish was a feeble: "Gnaaah!"
Now everybody knows in hell the official language is German, thus no dark bear has ever had problems pronouncing the call. Little Griffin however grew up in New York, and he had never heard a rolling R in his young life. He tried hard, and after years of schooling and training camps his call became loud, strong and well respected, but remained: "Gnaah!".
It broke his fathers heart. But the future had a lot in store for young Griffin, and over time his father, who had turned white, would learn what a fine son he had, that his son was in fact the most famous bear in the world, and everybody knew his name and spoke it with honour: Griffin, the dark bear from hell who goes "Gnaaah!".
