Eeyore is described as an "old grey donkey."
He is always depressed. The
biggest problem that Eeyore had is, that his tail falls off.
He lost it many
times. His
other problem is, that his house pours in, he had rebuilt it, again and
again.......
Christopher Robin is able to reattach the tail with a drawing
pin.

Eeyore is apparently able to write, or at least recognize
letters such as the letter A that he teaches to Piglet in the
fifth chapter of The House at Pooh Corner.
He spells his own name "eoR" when signing the "rissolution"
that the animals give to Christopher Robin as a farewell present in the
final chapter of The House at Pooh Corner.
Eeyore also wrote the awkwardly-rhymed poem called, "POEM",
which appeared on the "rissolution", making him the only character
in the Winnie-the-Pooh books other than Pooh himself who
attempts to write poetry.

Eeyore is also surprisingly good at the game Poohsticks,
winning more times than anyone else when it is played in the sixth
chapter of The House at Pooh Corner.
Eeyore lives in the southeast corner of the Hundred Acre Wood,
in an area labeled "Eeyore's Gloomy Place:
Rather Boggy and Sad" on the map in the book.
He has a stick house there in which collapses rather regularly,
called the House at Pooh corner,
which Pooh and Piglet built for him after accidentally
mistaking the original house that Eeyore built for a pile of sticks.
He has a poor opinion of most of the other animals in the
Forest, describing them has having "No brain at all, some of them",
"only grey fluff that's blown into their heads by mistake" (from
chapter 1 of The House at Pooh Corner).

Eeyore's favorite food is thistles.
Eeyore appears in chapters 4, 6, 8, and 10 of
Winnie-the-Pooh, and is mentioned in a few others.
He also appears in all the chapters of The House at Pooh
Corner except chapter 7.
Eeyore's "birthday" is May 10, 1871, the date when he was
made.
That's why he is always quiet, but he is a very intelligent
animal, who keeps that knowledge mostly for himself.
He will
always reminding on his birthday.
The voice of
Eeyore was from Ralph Wright in the Disney Winnie the Pooh movies.
