After the rain these plants are full of snails. They love to eat the flowers. This time my daughter and I spotted some without a shell/house. But she had a two shells in her room which she left on some leaves with the words: "maybe they like it and can reverse back in". Almost 9 and I still love the way she thinks! Then came the questions, so we might need to do some research on snails this weekend as I couldn't answer them either.
