E had already fallen asleep at night, and S was still not sleepy. He told me that he wanted to make a craft and asked me to search for a craft online. I had many toilet rolls cardboards to be recyled, so I googled up "toilet roll crafts" and came across a toilet roll snake craft on this website and tried to follow it. We used a kitchen toilet roll cardboard and cut following the 'lines' on the cardboard.
S painted it green and left it out to dry overnight.
