It’s another sunny day at Forest Camp, the most wonderful place on earth - and Odo, his best friend Doodle and all the campers are enjoying another day in the sun. But something unusual is happening - the big sycamore tree, the acorn tree and the oak tree have just prematurely lost all their seeds before they’re ripe. The birds feel the earth beneath them is shaking - something feels very wrong. They discover that huge metal beasts with bright lights are making their way towards forest camp and flattening trees in their path. Forest Camp is at risk. Their home and their community will be lost. Can Odo and his friends save it in time?
