"OMG! Tiffany!! Why are you trying to solve this case of a thief stealing clothes?!" Jessica yelled in anger.

"Because the place is near where we are trying to solve the other case, maybe this is related to it." Tiffany answered sticking out her tongue. Jessica face palmed and glared at Tiffany.

"But seriously!? A case where a thief is stealing clothes?! This is wasting our time!" Jessica yelled once again and slammed her hand on the table.

"We don't know that!" Tiffany said and picked up her phone, she nodded twice and out her phone away.

"Let's go and find that thief!" She said and grabbed Jessica by the wrist and pulled her out of the Police Station. They met up with the rest of the team.

"Hii Ppanii!" Taeyeon greeted which earned a slap from Sunny.

"Can't you be serious for once?" She asked and Taeyeon shook her head with a grin. Jessica sighed.

"Okay! Let's go!" Tiffany clapped her hands, they started to look around the town.

While they were looking, Taeyeon was out of sight. Sunny sighed and continued go walk alone.

"This is wasting out time!" Jessica said and continued to follow Tiffany.

"Ssh" Tiffany said and walked slowly.

All of them appeared in front of a tree except for Taeyeon.

Sunny jumped down from the tree with a cat and all the clothes that were stolen.

"Here is the thief." She said.

In a moment, Taeyeon jumped out from a bush causing Sunny to drop the cat, Tiffany caught it.

And poured honey on Sunny causing her outfit to be all sticky then dropped carrots on her.

Then started to laugh. "Hehe~ a bunny eating carrots and honey!" Taeyeon said and ran away.

"KIM TAEYEON!" Sunny yelled in anger and began to chase her.
