Grizzly Griller is a survival expert, really wild wildlife wrangler and Beanotown TV superstar.
He's Dennis's all-time hero.
He might also - and this is top secret, don't tell a soul! - be afraid of hamsters.
Yep. If Dennis actually ever grows up (he says he doesn't have to), he'll probably turn out to be something like Grizzly, who describes himself as:
And incredibly modest.
He is. You've probably seen him in action on shows like these:
The World's Most Incredibly Dangerous Supermarkets, with Grizzly Griller
Grizzly Griller's Stays Out Till After Nine
Grizzly Griller Versus Slightly Grumpy Animals
When Barbecues Go Wrong, with Grizzly Griller
Grizzly Griller Beats Bear Grylls At Snake-Wrestling
The last one hasn't been made yet, but Grizzly says he's up for it if Bear Grylls is.
