Interim head of Sayers Croft Forest School, Zoe Stroud, told PEOPLE the duchess was "lovely - although she said the only mini beast she managed to find on the hunt was a slug! But she did see a frog under a log."
Stroud added that Kate fit in easily with the children, adding that her own children Prince George and Princess Charlotte love to hunt for spiders in the garden.
“She really gets what we are doing here and said she often takes her children on spider hunts in their garden, which they love,” she added. “They can spend hours out there.”
What an odd activity for the royal children!
