Nell's big brother Lucas and his nerdy friends are camping out in the garden. They've got a fire and marshmallows and everything! Nell and Freddie Spoon are desperate to join in but they have to go to bed at eight-thirty. Eight-thirty! So they come up with a plan to sneak back out and play some tricks... They steal the marshmallows, and put a frog in a sleeping bag, but their best prank is to pretend to be The Beast of Bramble Woods! But Lucas catches them and they run off into the woods so they don't get told off. And then they get lost. And then they hear the noises. But it's just Lucas, isn't it?
