I took this a few years ago. I saw something wriggling in these leaves and upon closer inspection saw this Earthworm. Worms are interesting little things and great for the soil.
Got a good report from the physio today. Ankle is moving and now time to strengthen the muscles. He also said I can walk in the house with my trainers again and to stop using the crutches so much and keep the bad ankle moving. So all good and happy with this.
