>The sound of hooves clopping down the halls rung out in the castle. >Giggles followed the clops, sometimes breaking out into full-on laughter. >Feathers ruffled and flew about in the air. >"I've got you now, Luna!" >The blue alicorn's laughter rang out throughout the castle. >"N-no, stah-hahaha!" >A feather floated over to Celestia's body and danced about on her coat. >"Oh no, L-Luna-hahaha!" >"Give in S-sister! You are corner-whahaha!" >The moon princess squirmed in an attempt to get away from her sister's feather. >The white alicorn, on the other hand, was still laughing from being tickled by her sister. >"I'm not giving up, haha, Luna! Take your tickles like a p-princess!" >"I implore you to do th-haha, th-the same, Celestia!" >"Celestia's feather moved under to Luna's belly, which was her most sensitive spot. >"Sister, no, I beg of y-HAHAHAHAHA!" >Luna's feather dropped out of her magical grip, and fell over on her back. >The older sister had the upper hand now, tickling her sibling with no mercy. >She wiggled the feather all over the moon princess' belly, inciting loud guffaws. >"N-ahahaha, n-n-no! I-I, I CONCEDE!" >The feather moved away from Luna. >"So, do you accept that cake is infinitely better than pie?" >"I would never-" >The feather moved back over to the blue alicorn's sensitive belly. >"Bwahahahaha! Okay, okay, cake is infinitely better than pie! I, ahahaha, Princess Luna, declare it so!" >The feather goes back to Celestia. >"As I thought. Thank you for agreeing with me, sister." >In a flash, Luna plucks another feather off of her wing with her magic and attacks Celestia with it. >"Now admit that blue is a better color than yellow!" >"Bwahahahaha! Never!"
