"Is the new Knuckles more ticklish on his buffed upper body while the old Knuckles is more ticklish on his bigger feet? The world must know!"

This is a question that  chameleonice asked while I worked on this pic, which started out as just something fun. Both were to have their feet tickled, however, I noticed that old Knuckles does look like his feet are bigger even when you take the differing proportions into account. And Boom! Knuckles feet do also look smaller than Classic Knuckles. So, why not try and provide an answer to Cham's question? ;) It may look like Boom! Knux is more ticklish, but Classic! Knux is more stubborn, I doubt that he's having any easier of a time. =P

Hmm, I think we need more data before we can find an answer to Cham's question, personally. ;) Just means more ticklish fun for these two. Which is fine by me, as far as I'm concerned, Knuckles doesn't get enough tickles compared to most Sonic the Hedgehog characters.

Btw, I find it immensely amusing that Sonic has his own submission theme under fetishes/other, says quite a bit about his fandom once you think about it. ;)
