Golden Sun/Tolbi

Tolbi is one of the largest towns in the game, and is home to the Colosso tournament, a Romanesque gladiatorial combat event. Tolbi is ruled by Babi, a mysterious man who has been leading the city for over a hundred years.

Tolbi Docks
Once the ship lands, you can depart. Before leaving the dock area, you will see two tall boxes. Move one of them two places to the left, and the other 1 spot to the left. Climb up the stairs and jump across to get a treasure chest containing a Potion. Once this is done, you can go on to Tolbi.
