Locomotionless is a quest in Mario Party Advance that starts at the Train Station. It is initiated when Shy Guy, who works at the station, asks the player for a favour; if they decline, Shy Guy apologizes for bothering them, while if they ask about the favour, the quest promptly begins. Once the player asks, Shy Guy thanks the player before explaining that the train station has run out of Coal for the only train. Shy Guy needs the player to pick up some coal for him, elaborating that it can be found in the Town Area but not at the item shop, Junk. The player is then sent off to obtain some coal, though if they return, Shy Guy bluntly tells them that the coal can be found at the Vending Machines. The vending machines only sell coal (a play-on-words of "coal" and "cola"), and the player can pick up a sack of coal without paying. Shy Guy is happy to finally have some coal once the player returns with the sack, rewarding them with the Cake Maker Gaddget and thanking them multiple times, which concludes the quest.
