Trick or Treat! Halloween Party!(トリトリ! ハロウィンパーティー!) is a Making Drama first performed by SoLaMi♡SMILE in Episode 17. It is the first holiday themed Making Drama and the 3rd making drama performed by SoLaMi♡SMILE.
The room starts dark with three large jack-o-lanterns revealed. The camera zooms into one to reveal a purple and orange scenery full of black gnarled trees, several bats, a crescent moon, and ghosts wearing hats. The girls appear with bat wings, with each getting a turn to speak before they grab hold of the moon and spin it. As the girls pose they float away as it transforms into a large lantern and out flies candies, cookies, lollipops, bats, and ghosts holding lanterns. The three Idols then pose with a different object, one holds a pumpkin, one has a container of candy, and the last holds one of the ghosts.
