Hi! After defeating Crocodile, buy Nami's Desert Dancer Outfit in Nanohana, help Toto dig three times in Yuba with the shovel, and rebuild his bar with 20 Wood, 10 Beer, and 200 Berries. During the day, choose Dancer Job with Nami and complete Sensual Dance first; Erotic Dance requires Lust above 15, and Hot Dance unlocks after that with Lust above 25.
