1x17 - Doraemon

Cry baby Nobita has boasted that he will enter a stilt race tomorrow but he does not know how to walk on stilts so Doraemon goes to the 22nd Century to get him a cross between a stilt and a horse. Gian steals it so Doraemon becomes a tough teacher as he trains Nobita to walk on stilts. The mechanical stilt horse runs amok in Gian's house.
