Grizzly Griller has a brand new survival show that Dennis is obsessed with! 

Dennis, having memorised Grizzly’s latest survival guide, takes his friends to explore Beanotown forest and become a part of the show. 

But when they track down Grizzly Griller, they see him losing a fight with deadly Beano snake – one swift bite, and the snake’s toxic venom causes instant memory loss!

Now, with Grizzly wandering around the forest lost, Dennis and the gang have to use their survival knowledge to track down their hero and bring him back home.
