Part-Timer

The Part-Timer is a character in Majora's Mask. He can be seen working at at the Trading Post after 10 p.m., but is also found during the day in Termina Field trying to catch three red Rupees on a tree near the Astral Observatory. If Link hits that tree with a rolling attack, the Part-Timer will fall and hit the ground, dropping the three Rupees and claiming that he stole it from a crow.

When the Man from Trading Post leaves (presumably to work at the Curiosity Shop), he leaves the Part-Time Worker in the Trading Post to sell things. The man very obviously doesn't really care about the job, and doesn't know what any of the merchandise is. However, he is very susceptible to masks: if Link wears the Zora Mask, the Part-Timer mistakes Zora Link for Mikau and states that he too is in a band, he also claims that he wants to attend The Indigo-Go's concert in the Milk Bar during the Carnival of Time. When Link wears the Deku Mask, he ignores Deku Link. When he wears the Stone Mask, the Part-Timer wonders why the Trading Post has so much money if business is so slow. When Link wears the Couple's Mask, he will show a desire to find a girlfriend and get married. When Link wears the Postman's Hat, he says how he entered a contest for some concert tickets and is wondering if he's there to deliver them.

His Ocarina of Time counterpart is the man looking at Death Mountain on a roof in Kakariko Village. He gives Link a Piece of Heart when Link talk to him after he managed going on top of the roof by using the Hookshot.

Trivia
The Part-Time Worker shares some of his characteristics with Baito from The Wind Waker.
