Heh heh...this is my all time fav KnucklesXRouge moment from Sonic X
She's gonna tickle him to DEATH D: LMAO
Hearing Knuckles laugh so hard was HILARIOUS
Sketched then detailed and shaded in my sketch book and cleaned up a bit in photoshop.
(p.s. I the show they didn't actually let you SEE Rouge tickling him, but you could hear it XD )
Knuckles and Rouge (c) Sega and the Sonic Team
