The thing with tricksters is that if you figure out a way around what they're asking, they'll take that thing and be greatly amused by it. Instead of being offended by the spell that hooks its way into the corruption-souls and yanks them out, he's merely amused, cackling madly.

"Crafty little lamb!" He laughs, and there's the sound of water sloshing again as he spins around and becomes something far larger than he was moments ago, something with too many limbs and a snakelike body beyond the fog. "Very well, you can have your little shrimp's soul back."

There will be a moment while Callan extracts Clotted Cream's soul from himself. Souls are odd, malleable things, so there's some squishing and squashing going on before Callan somehow balls this thing up. Wearing a cheshire cat grin, all he says is:

"Catch."

YEET!
