Lotta has a kind and caring personality, especially towards her 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).
She has a hoard of pet rabbits.
Lotta used to be called "Lil' Lotta" because she was the tiniest kid on the block (even tinier than Tiny, who back then was called "Tiny-ish). This was until she hit a growth spurt.
