Koopa Legends

Koopa Legends is a special item found in Paper Mario.

After Kooper joins Mario and his party, an elderly Koopa Troopa named Koopa Koot has a favor for Mario. He asks that he wants to borrow this book from Kolorado, the only Koopa in the village who has a copy of it. To get it, Mario has to ask Kolorado's wife to retrieve the book. After finding it, she will give it to Mario, mentioning that the book was found behind her husband's bookshelf. She also mentions that it is a strange book that contains pictures of Koopa Shells and exercises, and one of its captions is "Firmer shells in 30 days". Mario then has to give the book to Koopa Koot, who rewards him with a single coin.
