Which Doraemon episode was about a tree-seed thingy which became a girl?


There is a tree-seed kind of a thing which Doraemon gets even though he did
not buy it from the 22nd century. He tells Nobita not to use it, but he does
and makes a girl. Now the girl is getting attached to Nobita and they don't
know what to do. Finally, an old man sees her and realizes that she looks just
like his dead daughter and so he adopts her.

Which episode was this?




These are the two I can find. The 1973 version did not adapt this story. Both
are without subtitles though.

As for the summary you want, I was only able to find a Chinese version.
