S1·E123 Moving Everywhere

Nobita is jealous of a boy who has moved many times as he has always lived in the same place. Doraemon uses a model flying house which when it finds an ideal place, can move their house there. After two bad choices, Nobita moves the house out into the country where he and Doraemon play in the forest for a while, then back to the city. However, his mother has left the house and is now marooned miles from anywhere.
