Who is Fortuneteller Baba?

Bulma finds there is nothing wrong with the dragon radar and thinks something organic may have swallowed the ball that puts the ball off detection. Roshi suggests Goku visits Fortuneteller Baba to find the last Dragon Ball with her clairvoyance. Goku takes off with Yamcha, Puar and Krillin. They stop at a town and Goku needs to get a new suit of clothes. While a new martial suit is being made, Goku takes Upa on the adventure with him. After changing into his new clothes, Goku and his friends head off to Fortuneteller Baba's palace, passing desert tornadoes and storms. They are greeted by Fortuneteller Baba's assistant Ghost at the palace. A group of mean-looking visitors enter the palace and leave in a devastated state. Goku and the others enter and meet Fortuneteller Baba herself who is not what they expected. Baba is asking a huge price for a single fortune and Goku's only alternative is to battle five warriors of Baba's.
