Ooccoo Jr.

Ooccoo Jr. (おばちゃんの息子 Oba-chan no musuko, lit. Aunt's son) is a character in Twilight Princess and Ooccoo's only son. By returning him to his mother, he allows Link to return to a certain point inside a dungeon. He is a member of the Oocca tribe, and apparently the younglings are nothing more than disembodied floating heads. He speaks very little, and this is evident in his letter to Link after the completion of City in the Sky.

Ooccoo Jr. appears on Ooccoo's trophy in Super Smash Bros. Brawl.

Trivia

 * In Twilight Princess, if Link uses Ooccoo and Ooccoo Jr. in the first dungeon he finds them in, the letter that he later receives is different than if he hadn't used them. It is possible to get both the letters if Link doesn't use them in the first dungeon, but later uses them in any dungeon afterwards before the Temple of Time.
