|First appearance||Skyward Sword (2011)|
After Faron floods the Faron Woods to eradicate the Bokoblins in the area, the other Kikwis become delighted at the newfound peace; however, Oolo remains paranoid that the monsters will come back. Seeking a new plant species for Owlan, Link brings Oolo to Skyloft with the aid of LD-301S Scrapper, where Oolo is told that he will be safe. Owlan, dumbstruck and fascinated by Oolo, gratefully rewards Link with five Gratitude Crystals.
As many Kikwis seem to be named after varieties of tea, it is possible that Oolo is named after Oolong tea.
