Tolstar

Tolstar was a greedy trickster found in Stardust Fields in the game Mario & Luigi: Superstar Saga. When Bowser got stuck in a cannon, Tolstar charged the brothers all of their Coins to keep the incident a secret. Mario offerd up the coins, but they are all Mushroom Kingdom coins, and worth much less in the Beanbean Kingdom. Tolstar demanded 100 Beanbean Coins and the brothers had to search Stardust Fields for them. Upon collecting them, however, Tolstar still refused to set Bowser free and attacked Mario and Luigi.

In battle, he attacks by throwing spiked balls at Mario or Luigi, and even gives a hint by saying that remembering which hand he throws it with won't help them.
