If Gian's a Superman - S1.E94

Gian grabs a "superman" cloak off of Nobita who has grabbed it from Doraemon, and puts it on. It gives him the power to fly when someone blows a flute, but it is cursed in that he must help one hundred people before he is able to take it off again and even if the bath will still have to go if a flute is blown.
