How to Complete the Quest
Manny asks you to talk to Prima in the Ton Pu Inn on his behalf. Go into the inn and step behind the counter to talk to Prima. Ask what she likes. Then go back outside and talk to Manny. He asks for 10 Restless Crickets. You can find some in the fields northwest of the inn. After you have 10 of them, talk to Manny again to get a Silver Rupee.
