I ran a game for my kids last night. We played a quick Christmas-themed game where the Ice Goblins had abducted Santa in order to ruin Christmas and steal joy from the world.
...at least that was my original story.
You see, my 7yo added that they'd also captured Mrs. Clause too and they were putting them in machines to send them to different universes... WHICH IS SO RAD. (Thank you #IntoTheSpiderVerse)
So with the holiday theme in mind, my 4yo was Rudolph...who could also turn into the Hulk and a tornado for some reason. My 2yo was Frosty the Wizard Snowman (okay, so I helped him a bit) and my 7yo picked Penny, an elf "fire gymnast" which is essentially a ninja with fire magic.
