The Lion's Tail is an item in the DOS and Deluxe versions of Mario is Missing!. It is a fragment of one of the lion statues that sits in front of the Palacio de las Cortes in Madrid. It is stolen by some Koopa Troopas when they rampage through the city, then taken back by Luigi as he wanders throughout the city. As he does not know where the Lion's Tail belongs, he proceeds to show it to Madrid's citizens as he walks around. Everyone recognizes its origins from the palace's lion while also telling Luigi other facts about it, such as how the palace was constructed in 1843 (it was actually built from 1843 to 1850). Luigi uses this information to successfully return it through the palace's information booth, and he is rewarded with $2520.
