Shizuka-chan Became the Elephant's Nose

Shizuka witnesses Gian, Suneo and Suzumu being unreasonable to the girls while they share a space at the open lot, and with Nobita not brave enough to deal with them, she seeks Doraemon's help to stand up to the boys. He gives her an Elephant Trunk Lipstick so she could help others in need, but she has to avoid exposing her identity as the Masked Elephant Trunk Girl. Soon she exhausted with helping others and returns the lipstick to Doraemon, but when Nobita is tied up by the boys at the mountain, Shizuka dons the Masked Elephant Trunk Girl costume for one last time to save him.

Nobita feels embarrassed because he is rescued by the girl, so he goes to ask Doraemon to give him gadget. Doraemon says that there was only one Elephant Trunk Lipstick, but Nobita doesn't believe it. The three girls say that they will really protect them this time, but the gadget they takes by mistake are Octopus Ink Lipstick, and instead they spray the three girls with ink.
