Lotta has a kind and caring personality, especially towards close friends and animals. She can also be frightened very easily. She takes friendship seriously and will do anything to keep her relationships stable. She likes befriending others as well. She refers to herself as "the snuggler and cuddler of Harvey Street."
Lotta sees the beauty in everything and everyone, which causes people to take advantage of her sometimes. She is also a softie for any cute animal, as she describes herself as "friends with all animals," who usually come to her when she needs help (however, the only exception is raccoons).
Audrey and Lotta are best friends. They met by crashing into each other when going to the tree. They seem to be complete opposites as Lotta is more carefree and Audrey is more brave and tough. Lotta tends to be amazed at what Audrey can create.
