Twins through the ages!
The one on the bottom right is them in 8th grade. I head-canon that Dipper finally got a haircut and it looked HORRIBLE so Mabel cut hers in solidarity
The one on the bottom left is in Freshmen year when Mabel is finally the taller twin
The one on the top right is sophomore year with Alex Hircshe’s emo Mabel
The one on the top left is Junior year, which is my favorite Dipper
