Potential Tickle Pets

So here's a big piece of fan art for a bunch of friends and their wonderful OCs. OCs we don't see tickled enough <3

In order from left to right we have:

's Paula. Who is an adorable gal who's getting a very soft and fluffy torment. Her toes and soles teased by soft-flosser ropes.

's Kylie, who's no stranger to devious tickle torture. Her lovely soft soles are teased by scratchy, merciless clawing forks.

's Seph. In typical Inkling fashion is having her soles "painted" by an opposing color. It's gonna take a while to paint them 100% though...

's Character Titania, who I just love to bits and want to see endless works of her tickled. She's getting a harsh treatment of oilings and prong strokes to really drive her to squeak!

's Character  Tabitha. Who's getting the lightlist of teasings. A few curious and wiggling feathers! 

Which do you think would make for Mage-Caroo's best tickle pet? And why? :3

Hope you all like the line-up!
