From Nookipedia, the Animal Crossing wiki
Jeremiah (クワトロ, Kuwatoro) is a lazy, frog villager in the Animal Crossing series. His name comes from the lyrics "Jeremiah was a bullfrog" in the song Joy to the World by Three Dog Night. As well as being featured in every Animal Crossing game, he is also featured on the City Folk official poster, running down a hill behind the City.
Jeremiah is a light blue frog, with two large blue circles on his face: one on and around his right eye, and another on his lower-left cheek and jaw. He also has a squiggly mouth, which makes him seem as though he is eating something (this relates to the traits of the lazy personality). He will be commonly seen with his eyes closed, which make him seem like a relaxed character, but when they open (usually in reaction to something shocking), he is shown to have black, beady eyes. His color scheme is the inverted version of another villager with the same personality.
Below is a brief description of the lazy personality. For more information, click here.
Like most lazy villagers, Jeremiah loves to eat and sleep. He gets sad if the player reads his letters or hits him with a net, but is usually happy. Jeremiah won't get along with jock villagers since he hates exercising and eating healthy, while the jock villager loves to do that. He won't get along with snooty villagers, either, since he doesn't care about his appearance, while snooty villagers do.
Jeremiah lives in a normal-sized house which is furnished with items from the Froggy set, including a Froggy chair. If the player visits his house, he sometimes gives the Froggy chair as a gift. His house also includes a barbel steed. He has a red boom box that plays "K.K. Mambo."
