The Tranquilizer Stick or the Chill Out Stick in the English dub, is a gadget which was used in the episode Now-Now Stick. It has an ability to tranquilize someone angry. Doraemon gives it to Nobita who uses it to tranquilize Gian and his mom (and some other angry people in 1979 anime episode). Later, Suneo steals it from Nobita and uses it on Gian again and again.
User attaches the stick to the target's mouth and says "まあ まあ! (Calm Down! Calm Down!)" and then target calms down. This gadget hides the target's anger inside of his/her body. The target's anger gets stuck inside his/her body and it grows little by little, then it explodes like a volcanic eruption if the user used the gadget too many times on a person.
