This quest is available starting in Chapter 4.
Talk to the boy on the wooden decking west of the Arganan Bridge. He says that if you catch 3 frogs, he'll teach you a secret. Go to the fortune teller, and she'll tell you the location of one. You need to enter in and out of a building as you can only talk to her once. The frogs spawn in each area once. To catch a frog, you must slowly and steadily approach one from behind and press A. When you catch it, it gives you a 5 movement speed boost. There are 6 in all, but only 3 are required.
Location of frogs:
- Riverside wood deck
- Well behind Ariela's Tavern
- Fountain at Castle Gate Plaza
- Fountain Plaza
- Well near the Eastern Gate
- Well in the area north of Central Plaza, behind the Dye Shop.
Reward: Ability to dive in the water and 30+ movement speed (optional).
