Flora has had the same idea and the company has pulled off a stunt on a massive scale with an enormous 13 metre long model of a diplodocus made entirely from plants - the Florasaurus. They're hoping to help kids to get back in touch with where their food comes from by demonstrating how some of the biggest and most magnificent creatures the world has ever seen were powered by plants.
Florasaurus took a tour of London last week. If you'd like to visit him (or perhaps it's a her!) yourself then you can do so at Westfield Stratford, London, between Friday 25 March and Monday 4 April (apart from Easter Sunday) or at Manchester's Trafford Centre between Thursday 7 April and Sunday 10 April 2016.
It's free to visit Florasaurus and you'll also have the chance to take your photo with the giant dinosaur, enter competitions and take part in activities made with the help of the Eden Project.
