Baljug is the prehistoric counterpart of Baljeet Tjinder.
He was one of the five kids, along with Phinabunk, Gerb, Isabelock, and Boofgard. Together, they made their own wheels and put them together as one big cart and rode it through town. Later on, at the end of the day, when Can-tok made a fire, he, along with his friends and the caveside girls, sang a caveman version of Gitchee Gitchee Goo in celebration.
Baljug is physically identical to his present-day self, except his hair is larger and messier, and he wears what appears to be a prehistoric equivalent to a head band. He wears a grey dinosaur skin that stops at his knees.
- He is from 27,000 B.C.
- While Baljeet is consistently shorter than Phineas, Baljug is quite a bit taller than Phinabunk.
