Ash, Misty, and Brock were leaving Ecruteak City after defeating Morty and his Ghost Pokemon. The next stop was Olivine City and the Olivine Gym. While on their way, they decided to take a pit stop at a Pokemon center. They were greeted as usual by the Nurse Joy inside the Pokemon Center.

"Hey, kids. How can I help you today?" Nurse Joy asked the trio with a smile.
Brock immediately ran over to Nurse Joy and grabbed both of her hands.
"I don't know if you can help my friends here but I can think of a few ways you can help me Nurse Joy!" Brock had hearts for eyes and was up to his usual antics before Misty grabbed his ear and carried him off somewhere.
"Sorry about Brock, he gets like that. Could you check up on my Pokemon Nurse Joy? We just came from the Ecruteak Gym and would love a nice rest for a little while." Ash explained and asked the pink-haired nurse.
"Sure thing. Would you like me to check up on your Pikachu too...er?" Nurse Joy didn't know his name yet.
"It's Ash, sorry for not saying that earlier. What do you say buddy, ready for a check-up?" Ash looked at his companion on his shoulder.
"Pika-pikachu!" The mouse Pokemon exclaimed and then jumped onto the shoulder of Nurse Joy. Ash then handed her the rest of his Pokeballs.
"Alright Ash, I'll have your Pokemon checked up in no time at all. There's no one else here at the moment so you and your friends can head into the Cafeteria for refreshments and snacks, I'll be right out!" Nurse Joy said with a smile and started heading towards the examination room.
"Thanks a lot Nurse Joy!" Ash smiled back and went to grab Brock and Misty to head over to the Cafeteria and take Nurse Joy up on her offer.

Meanwhile, the all too common Team Rocket trio was outside in the trees looking into the Pokemon Center, no doubt scheming a way to get all of our hero's Pokemon, or at least our little yellow friend.

"James, do you see anyone else beside the twerps in the Pokemon Center?" Jessie asked her blue haired companion.
"Nope, no one at all. It looks like beside Nurse Joy and the twerps its basically empty. The Twerp handed over his pokeballs and Pikachu over to Joy." James explained what he saw happen.
"Great, now we can't ambush him and take him by surprise if that's the case. We'll just have to wait then." Jessie slouched and sighed at the thought of waiting for another opportunity to steal Pikachu.
Just then, Meowth came up and used his fury swipes attack on Jessie. "Get ya head in the game Jess! This is perfect. If we can take Pikachu and the rest of the twerps little Pokemon while the innocent Nurse has them, then once we grab em' the twerps won't even know we took em! It'll be a lot easier stealing from her and a Chansey than the twerps and all their Pokemon by their side!" Meowth explaind his "brilliant" plan to the rest of his Team Rocket companions.
"Meowth you're a genius! I will get Weezing to use a smokescreen, we'll grab the Pokemon and get out quick on the balloon!" James said excitedly.
"Good thinkin' Jimmy now let's get this started!" Meowth grabbed the two of them and headed for the Pokemon Center.

Uh-oh. Looks like our favorite Pink haired character is going to be in trouble. Will she be able to hold off Team Rocket or will they finally succeed in getting Ash's Pokemon? We'll just have to find out next time.
