Mess solution
The items from the bingo cards can be found in the mess. Each set has a way to put the members in order:
| Baubles (7) | Colours of the rainbow |
| Candles (6) | Length |
| Holly (5) | Number of berries |
| Letters (6) | Name of sender |
| Shadow Santa (6) | Number of reindeer |
| Snowflakes (3) | Number of prongs |
| Snowmen (4) | Number of buttons |
| Trees (3) | Size |
If you trace a line between the elements of each set in order they should form a letter. Put these letters in order using the shapes on the pamphlet noticing that they correspond to the shapes decorating the jokes on the bingo cards (the square is used twice). They spell the message ELF IN CODE.
