Escape the Sunken Submarine Day 22 Advent Calendar

*CONTAINS SPOILERS*
Join me as I solve the day 22 puzzle for the Ravensburger Advent calendar, Escape the Sunken Submarine. If you own the calendar and want to try it without being spoiled then DON'T watch this video first! :) I'm also solving two other calendars, the Exit the Game 2022 puzzle calendar, 'The Hunt for the Golden Book', and this year's Escape Advent Calendar, 'Puzzling Round the Christmas Tree' - but these are each in separate videos.

Wow that was a lot easier than some of the others

There should be a red herring door in all of these calendars, to stop the last one being too obvious.
