Lotta is not really much of a tomboy as you may think, be she does show some traits of being one. She likes more manly sports and activities, wears whatever clothes she likes, even if it isn't more lady-like, and she does like to mess with people sometimes, but not much. She does, however, try to be nice to others and does have some proper standards.
Jade, on the other hand, is the smarter one of the gang. She, even more then tom jr., knows the problem of an issue and would try to fix it, but it mostly gets worse due to the acting of the others. She's not a smart girl stereotype as ahe does like to hang out with betty and lotta, but tom jr., and try to get onto her antics.
Both of them like hanging out with betty and like to get into whatever hits them. However, while lotta, for the most part, acts with betty, sometimes being a bit worse, jade gets a bit annoyed when they get in trouble and have to find a way out of the jam.
Lotta and jade match with betty as a main trio. The three pieces of the tri-force. Betty is the more excited one, lotta is the mostly trouble maker, and jade is the smarter and support. Sorry for the wait. Been busy with a few things.
