Actually Lucca's the one with the purple hair, Marle's the one with the ponytail.
Still, I wouldn't mind seeing Marle get tickled sometime, since she's always running around in sandals, and I'd think she needs to take them off once in awhile.
Thanks a bunch for this, Snail Shell. I've always liked Chrono Trigger. I'd love to see Lucca or Marle tickled at some point, but it's nice to see Ayla tickled too. Great pic.
