Advent-urous squid

I realised that I had not got the advent calendars for the family and when I went round the local supermarket yesterday they had all gone. The shelves had been full of them a day or two previously but I presume that now we are a few days into December they were removed.

I need not have worried and better to not intake chocolate daily! Our daughter had made this advent calendar for her wife based on squid facts - a different one behind each home-made door. The facts I have seen are fascinating - and nothing suggesting it is part of Squid Game,
