Lottie (タクミ,Takumi?) is a character that made her first appearance in Happy Home Designer. She is Lyle's niece, and has her own amiibo figurine. Lottie will be at Nook's Homes to help the player out on their first day, having them design her room as practice. Afterwards, she helps the player take on their first client. She also has a huge crush on Digby.
When the player is done with their first client, Lottie allows them to go outside of Nook's Homes to scout clients out for themselves.
Lottie also introduces all the new items the player can use slowly. She is the one that introduces anything and explains it all. On some days—usually when the player starts playing the game later in the—Lottie will have small black eyes with no eyelashes, and a greyish purple bow instead of a bright blue one, as well as dark blue shoes. She tells the player not to look at her, for she doesn't have makeup on because she woke up late and didn't have time to put it on, and she says she only wears makeup to impress Digby.
Lottie was added to New Leaf in the Welcome amiibo update. She gives the player a Nook's Homes model if you own Happy Home Designer. She also gives the player a tutorial on moving furniture via the touchscreen after the secret storage room has been added.
Although Lyle and Lottie have a difference in appearance from Pascal, all three characters are otters. Pascal is a sea otter while Lyle and Lottie are river otters.
She seems to have a crush on Digby, as shown when Tom Nook introduces him to the player, she has a heart appear over her head as she turns her head to Digby.
The official Animal Crossing Twitter account (Under Isabelle's name) has been temporarily changed as though Lottie is using it, since August 20, 2015.
On some uncommon occasions, Lottie can be seen without makeup, with a different color headband and pair of shoes on.
When Lottie walks around, it makes a sound different than other characters. The only other character who shares this trait is Isabelle.
If you scan Digby's amiibo and design a house for him, the next time you visit Lottie will be there and he will say that they are on a date.
