Kid Luck, still travelling with Old Timer, arrives in Mushroom City. After months in the wild, they're both glad to find a place where they can have some fun! While the old gold miner has every intention to enjoy himself, though, he immediately sends Luke... straight to school! A horrible sentence for the young cowboy-in-the-making, who is about to meet a quartet of already nasty little brats, and a pistolero with somewhat...flexible morals!
