Rex is the little dinosaur who shows children that being small is no reason to think small. Every story starts with something Rex notices and ends with something he understands — and a roar.
Fern Valley is built for ages three to seven. Nothing in it is scary. Every friend carries one thing worth learning: Dot counts and sorts, Skye looks closely, Bramble keeps trying, Professor Fern names the world, and Rex asks why. The games on this page are free, need no account, and collect nothing.
Books arrive in paperback first: picture books to read aloud, and activity books for pencils and crayons. Films and songs follow, the way they do in Rex's cousin world, Princess the Unicorn.
