A sequel to “Mouse Trap”.

It was 1 hour to the fashion show. Today, they were going to model costumes designed by Cocoa Pommel. She hired Silk to help her show off her costume, in hopes she would get more work. Silk was worried. Topaz has not shown up yet.
“Oh, where could Topaz be? It’s not like her to be late.” Said Silk.
Soon, she heard the door open. There was Topaz, but she wasn’t looking so good. She was a mess. Her mane was every which way, she had bags under her eyes, and she looked like she was going to fall over.
“Oh, Topaz! Where have you…” Before Silk could finish, Topaz let out a sneeze.
“I’m sorry Silk sniff I don’t think I will be a.. ACHOO!!” Said Topaz, in a sickly voice.
“Oh dear! Who will be able to wear the costume I designed?” Said Cocoa, and pulled out a black and gold dress with a gold skirt with a feather petticoat, and a matching hat and necklace, to go with the outfit.
Silk pondered. She didn’t know who could wear the dress.
“I thinkcough Tickles should be the one to cough wear the dress.” Said Topaz, who’s cough was starting to sound a little fake.
“Oh. I don’t know…” Said Brainstorm.
“Please? Do it for everypony?” Said Cocoa, looking quite adorable with her eyes.
Brainstorm couldn’t say “no” to that face.
“Well, if I really have to…” Agreed Brainstorm.
Cocoa smiled, “Oh, thank you Tickles!” Squealed Cocoa, and started giggling.
“Are you sure you can do this. This means you’ll be going first.?” Asked Silk.
“Honestly, I am not so sure, but the show must go one.” Said Brainstorm.
“Well then , there is no time to waist. Let’s get you dressed!” Said Silk.
And they rushed to Brainstorms dressing room. Topaz watched, as they left.
“Good luck Tickles. cough cough* You’re going to need it.” Topaz said, and made an evil smirk.
It was five minutes to show time. Brainstorm was feeling rather nervous. He had never been first in a fashion show before.
Suddenly, Cocoa walked up, “Thank you for filling in for Topaz Tickles. I’m very grateful.” She said.
Brainstorm smiled and looked at Topaz, who had a good view of the runway. She was coughing and waved her hoof at him. Brainstorm was starting to get suspicious, as he used to fake sick when he was in elementary school. He wondered if Topaz was faking sick. But then, the lights dimmed.
The fashion show began. And after announced the first costume, Brainstorm stepped onto the runway. The gold glimmered in the light, the necklace shined, and the feathers swayed to the movement of his hips. He made the dress look wonderful. Backstage, Topaz snickered.
Her plan was ready to be put into motion.
“Now, let’s let the audience know why they call you ‘Tickles’.” She said, and she lite up horn and focused her magic on Brainstorm.
An aura formed around the base of one of the feathers, and plucked it from the dress. Topaz then levitated the feather behind one of his legs and lightly tickled it. Brainstorm’s eyes lit up as he felt the feathery feather tickle his leg.
“Hehehehe…” Giggled Brainstorm , and swatted at the feather with his tail.
The feather then, darted over to his other leg and tickled it.
“GAH! Hahahaha!! Ooh! Ah!” Laughed Brainstorm, and stepped over.
The feather then moved over to his forelegpit. Brainstorm closed it, thinking he had trapped the feather. Topaz saw, and decided to kick her magic into high gear. The aura then engulfed the whole feather and started to make it wiggle.
“Gugheee hehe…” Snickered Brainstorm, as he walked trying to keep his composer.
Brainstorm couldn’t take it anymore. He raised his foreleg, but that was a mistake. Topaz then saw an opening. An opening into Brainstorm’s dress that is. Without a moment to loose, she forced the feather into the side of the dress.
“EEEHH!” Squeaked Brainstorm, as the feather squirmed around in the dress.
Brainstorm twisted and twirled. His sporadic movements made it look like he doing some kind of dance. The audience loved Brainstorm’s ‘routine’, as it showed how free the costume can move. As Brainstorm struggled to leave the runway, Topaz wiggled the feather into his panties. Brainstorm looked at Topaz.
He could see her horn glowing.
“So, she WAS faking it.” Brainstorm thought, but Topaz’s plan was about to be foiled.
The feather tried to tickle him, but the tape he was wearing was preventing him from feeling anything. He then sashayed, remembering to put a little extra swing in his hip, back behind the curtain. The crowd cheering, as he went behind the stage. Backstage, everypony was congratulating Brainstorm for ‘her performance’. Everypony except Topaz.
She scowled at him. And all Brainstorm did was look at her with a smug face.
