Physically, Eyesore is described as an old gray donkey. In Ernest H. Shepard's illustrations, he appears to be about chin-high to Pooh and about hip-high to Christopher Robin. He has a long tail, of which he is very fond, but that he is also prone to losing Owl once mistakes it for a bell-pull. Christopher Robin is able to reattach the tail with a drawing pin. Unlike Pooh, he is said to be "stuffed with sawdust".
Eyesore 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 gray fluff that’s blown into their heads by mistake" (from chapter 1 of The House at Pooh Corner).
Eeyore's favorite food is thistles.
