After what happened with the strange light ball, the 2 former humans were now transformed into pikachus. 

"What happened to us?! We were humans before but now why are we smaller now?" Misty asked freaked out.

"I believe the light ball Pikachu was playing with turned us into pikachus." Ash said looking at his now small yellow paws. "And our clothing is too big for us to fit in our small bodies now."

Misty then saw a mirror nearby and tried to walk over there on 2 legs but fell face first onto the ground. Ash ran up to her on 4 legs to help her up.

"And Why can't we stand or walk on 2 legs anymore?!" Misty panicked.

"And it looks like we'll have to walk on 4 legs from now on until we change back to normal." Ash said.

The 2 then went to the mirror and saw their reflections. And Ash was right. The light ball changed them into Pikachus. This cause both Ash and Misty to scream in the air and started running around the lab panicking.

Just then the door opened and Professor Oak along with Tracey and Brock (Tracey's pulling Brock because he was flirting with Joys, Jennys and other girls again as usual and Brock acts a lot like Master Roshi from the Dragon Ball series) came in but notice that Ash and Misty were missing.

The former humans stopped running and panicking after they saw Oak, Tracey and Brock came into the lab.

"Aw Crap!" Ash yelled.

Misty tried to cover his mouth with her paw but it was too late, they noticed his voice and looked down to where the former humans were at.

"Ash? Misty? Is that you?" Oak said with confusion.

"Ya, it's us but why do you have that look on your faces?" Ash asked.

"I believe we need an explanation on what happened to you two and why your are pikachus."

"Right." Misty said with embarrassment.

So the 2 former humans told them that they noticed a light ball that Pikachu was playing with but when Misty had it in her hand, sparks of electricity coming from the ball and Ash also got his own hand shocked and they shrank and changed into pikachus. When they were through, Oak simply nodded his head, understanding everything.

"So Ash my boy, Were you a Pikachu once before you turned into one again?" Oak question Ash.

Ash nodded.

"It happened back in Johto where me, Misty and Brock met a witch name Lily." Ash said.

"And that's what happened." Ash said.

"I see. I'll find a way to change you two back to your normal selves. I'll be right back." Oak said. Then he left the room to find something to change the 2 former humans back to normal.

While Ash, Tracey, Misty, Brock and Pikachu were waiting for the professor to come back, A net came out of nowhere and trapped not only Pikachu but Ash and Misty as well. 

"Pika!" Pikachu yelled.

"What the? We're trapped!" Ash yelled.

The net the 3 pikachus were in pulled out of the lab and up into the air revealing it was Team Rocket that trapped them in the net.

"Team Rocket! Release Our friends now!" Brock yelled angrily at them.

"Prepare for trouble!" said Jessie. (I'm sure you know where this is going).

"And make it double!" said James.

"To protect the world from devastation!" said Jessie.

"To unite the people within our nation!" said James.

"To denounce the evils of truth and love!" said Jessie.

"To extend our reach to the stars above!" said James.

"Jessie!" said Jessie.

"James!" said James.

"Team Rocket at the speed of light!" said Jessie.

"Surrender now or prepare to fight, fight, fight!" said James.

"Meowth, that's right!" said Meowth.

"Wobbuffet!" said Wobbuffet.

Unfortunately they couldn't get away because Tracey's Syther slashed into the balloon and they were sent blasting off again while Ash, Pikachu and Misty went in a different direction. Luckily Brock released his Crobat to go search for them while Tracey tells Oak what happened.

Will Crobat find Pikachu and the 2 former humans? Find out next time on Adventures of Ashachu and Mistychu...
