"Eeyore's Sad Day" is the first segment of the sixth episode of My Friends Tigger & Pooh.
When Eeyore goes unseen for several days, Piglet and Rabbit become concerned about him. They and the Super Sleuths discover him moping at the top of a hill. They learn that he's especially unhappy because the autumn has come and he can no longer roll in his favorite field of dandelions. They decide to try a variety of ways to cheer him up.
