Look away now if you hate the Elf!
We do have an elf but he originally came with a note saying he's a good elf and only there to observe, so moves around but that's it. Honestly, I could never be bothered with the time and effort it requires to make a mess which I then have to tidy up.
However, with this year being as awful as it, I thought I'd relent and have a naughty elf visit for a week. I know the DC will be thrilled and I figure I can keep it up for a week (although no longer!). I've purchased a new elf that looks different to the other one and thought, I might have both out at the same time or I might have the good one turn up when the bad one leaves after a week, I'm yet to decide. (The joys of lockdown and all this extra time on my hands
).
So what are the best naughty things your elf has done? I don't mind a bit of prep (hence this early thread) and I'm happy to do the bigger things seeing as I'll only have to do it for 7 days.
