And so it happened until Chrysalis gave in, begged for mercy and agreed to become Celestias pet.

Celestia’s Check list:  

Queen Chrysalis: Welcome to my dungeon Celestia, you have come where I put the most stubborn and resentful of prisoners that I capture, and as your punishment for refusal of surrendering your kingdom to me, you shall be tickle tortured until you die!
 
Celestia: HAHAHAHAHAHAHAHAHAHAHAHAHAHAHA (COUGH) HAHAHAHAHAHAHAHAHAHAHAHAHAHAHA (COUGH, COUGH) HAHAHAHAHAHAHAHAHAHAHAHA!!!!!!!!!!!!
 
Chrysalis: What’s the matter Celestia, too much torture for you, well it’s only to get better, coochie coochie coo!!!!!!
 
Celestia: HAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHA!!!!!!!!!!!!!
 
Chrysalis: I figured I’d get a ticklish princess with such cute soft feet, tickle, tickle, tickle!!!
 
Celestia: HAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHA!!!!!!!!!!!!! (now starts crying and sweating)
