Doraemon, 3

Since Doraemon left, Nobita has been feeling down. To make matters worse, Suneo and Gian enjoy tormenting him. Always the foresighted one, Doraemon left one last invention for Nobita before he departed: Lie 800, pills that produce the opposite effect of what the person taking them says. Nobita will not only get his revenge but also bring his friend back! Throughout this volume, they will experience many more adventures: robot elves who work while their owner sleeps will help Nobita, Doraemon will fall in love, and our two heroes will take photos of trips they didn't actually take...
