Опишите мэйбл из мультика гравити фолз (на ) (5 класс spotjight)

My favourite cartoon character is Mabel Pines from Gravity Falls.First time when you watch Gravity Falls you think that it is very easy to describe her-she is happy and not so clever.But when you watch other episodes of this cartoon you see that she is not so casual,you find new changes in her character.In every new episode you see that she becomes more clever and diligent.First she wasn't responsible,but in the end of cartoon she became very responsible person.
