Jinx is a Ghost character that has appeared in the Halloween 2017 doodle.
Jinx resides in an old abandoned house and is feeling lonely. Jinx tries to dress in a costume in an attempt to disguise as a Trick-or-Treater. Jinx later ends up befriending Momo.
Jinx makes a cameo in the Halloween 2018 doodle as a framed picture hanging on the wall in the mansion map. He is shown wearing a Witch's hat. This is reprised in Halloween 2022.
