Chatouiller les pieds!!!

(Disclaimer: As usual, this art is not by me. It's a detail from this picture that your can find here : www.deviantart.com/mistercobal… The artist's unfortunately not active anymore so it's a kind of tribute I pay)
A quite particular edit of my creation since it was partially hand made; I added the gloves and went over the lines, before adding the "clothes" with my drawing program.

So here are Knuckles and Sonic who've been imprisoned in tickling stocks made of bullet-proof, unbreakable glass, with their big soft soles offered to the tickles ! Of course people couldn't resist to see them helpless and rushed, Amy and Charmy arrived at first and got the privilege to tickle their feet first. The two guys instantly squirmed and screamed in laughter, being extremely ticklish on their soles, and the more they laughed, the more the tickles intensified, much to the pleasure of the crowd who savored their public humiliation. No one can wait to be the next one to tickle these tender feet !
