Damian Taylor says he's about an 8.5 or 9 on the ticklish scale, but honestly, I think he's even higher than that. All I had to do was touch his arms while he was strapped to the tickle chair and he started wriggling around and giggling like a silly girl. Damian definitely has an adorable laugh. He also has very ticklish feet and his armpits and torso are quite sensitive. Especially if I use an electric toothbrush and feathers. Damian had a lot of fun being tickle tortured and I think he liked it!
