yamenaa (momosuzu nene)
A mascot/caricature of Yukihana Lamy drawn by Momosuzu Nene at the request of Omaru Polka.
A white ball with an ^o^ expression, Lamy's signature heart ahoge and bowtie and the text "やめなー "(yamenaa, meaning "stop it" or "cut it out"), a catchphrase associated with Lamy and often thrown at Nene's for her rather immature (and quite inappropriate for an idol) sense of humor. It's sometimes drawn with Polka's arms.
