Potova & Joanna

Joanna and Potova are two girls who appear in The Wind Waker attending the School of Joy on Windfall Island. Potova is blonde, while Joanna is brown-haired. They will tell Link rumors if given a few Rupees: they will tell him that pots are hidden around the bushes of the island, give him information on the whereabouts of the wandering merchants, or trick him and tell nothing at all.

The Minish Cap
In The Minish Cap, Leila and Berry are two girls similar to Joanna and Potova that attend the Funday School. Leila, the one with blonde hair, is Simon's daughter (the Mysterious-Dungeon Simulation Game owner) and Berry's older brother is Romio. Link can fuse Kinstones with the two girls.
