Ideas for how to torment Clover, Alex, Sam and Mandy?
You've definitely come to the right place (Totally Spies is a real "guilty pleasure" toon for me).
My suggestion would be something that plays to the personalities of each character... Alex is the athlete, Sam is the smart one, Clover is the popular/vain one. So how about this...
Alex is in some sort of Bowflex-style tickling gym that stretches her out so lil mechanical hands and feathers can tickle her all over.
Sam is strapped down and is the subject of a tickling experiment designed to see just how much she can take.
Since they can't stand each other, and have the vanity/popularity thing in common, Clover and Mandy should be worked over together, perhaps by the PediTickle 5000 pedicure machine. This insidious device is laughter powered, so the harder Mandy laughs, the more Clover is tickled and makes her laugh harder, increasing the tickling of Mandy.
As this is a test of endurance for the girls (as well as a test of new equipment and techniques), this could be taking place in WHOOP's labs under the watchful eye of the girl's boss, Jerry (y'know he's always wanted to teach those three a lesson).
So that's my two cents worth...
Hahathna 😱
