The Elf had left his reindeer this morning (see here) and it took the girls some time to find him.
Eventually they found him hanging off the handle on the fridge door. What was he doing there?
The girls decided that he was missing the North Pole and so was trying to get in to the fridge to cool down. We know the feeling well!
It wasn’t until I poured the milk into a saucepan to make hot chocolate that we realised what he had done:
Both girls found the green milk hilarious. The Little One was a tiny bit disturbed by the colour, though, and even when I’d made hot chocolate, she wouldn’t drink it! She told the Elf not to do it again…
