In her treehouse den, Jess is looking at beetles. One in four animals on earth is a beetle, so there are plenty to look at. She has a close look at their hard shells, their sensitive antennae and the fact that they all have wings, though they do not all choose to fly. Setting off on a Minibeast Adventure, she meets up with some children and together with them searches for beetles in the woods. Looking under stones they are able to find one and have a good look at it. Jess shows how to make a tumble trap and they see what kind of minibeasts tumble into it.
