His name is shown in the New Leaf Prima Guide, but he does not appear in New Leaf.
Dozer is a purple bear with a bear shirt on initially, a play on the fact he is a bear. He has a curly black unibrow, similar to Claude's. He has a brown muzzle with a black and white nose. The inside of his ears are brown. He seems like he is in bed because of Dozer sleeping. His eyes are almost always closed, as if he's sleeping or dozing off.
Below is a brief description of the lazy personality. For more information, click here.
As a lazy villager, Dozer will be friendly and easy to get along with due to his laid back lifestyle. Like all lazy villagers, he has a love of food and relaxing. He will enjoy partaking in the usual hobbies, usually for relaxing reasons or for food, like when fishing. Dozer will get along well with other villagers, but may offend or confuse jock villagers, who have a conflicting lifestyle of exercise and fitness, compared to the lazy lifestyle of relaxing and food. He will get along with other lazy villagers with whom he will talk about food, comics, or superheroes. He will also get along well with normal, peppy, smug, uchi and other lazy villagers, and occasionally cranky villagers, but may from time to time annoy snooty villagers, who disagree with the lazy lifestyle.
In an official Animal Crossing poster featuring all of the villagers in New Leaf, the original version initially had a bunch of mistakes. One mistake was Nate being incorrectly labeled as Dozer. This was very odd, as this was the New Leaf roster, and Dozer hadn't been seen in an Animal Crossing game since Population Growing. Aside from them both being male bears, they look nothing alike. It had been fixed and everyone who ordered it got the revised poster for free along with an apology.
