In Kalos, Ash and friends are in a forest like usual. Serena was trying to find a way to be alone with Ash.
At night, the four were sleeping, Serena was dreaming she found a Ginnie lamp and wished that Ash would be alone with her in the palm of her hand. Serena stated she also wanted more.
In the morning Serena was being dragged by Clemonts a-pawn arm. Turns out she slept too long. They were in the next city. When they arrived, Clement and Bonnie ran off for some strange reason. Finally alone, Ash and Serena were in a unknown park just doing stuff, that was when Serena remembered the dream she had.
Then she had a strange feeling, she felt like she grew a little bit. Her outfit was a bit tight, her pants were a tad short. Next, she thought her breasts were bigger, the only reason she felt was because of the tight outfit. Other than that, it wasn't noticeable.
About an hour later, the two were lost. That's when Serena started to grow. She grew 5 inches with Ash noticing. "Serena, are you alright," said Ash.
Serena grew more but she was getting much bigger, her clothes were ripping like a chocolate lover ate a box of chocolate. Her breasts were noticeably bigger. This was not what Serena had in mind when she wanted more. In 30 seconds, Serena was 50 ft tall nude. Ash was wondering what happened just now. Ash noticed Serena was a bit muscular than before. Serena had a six-pack getting a little muscle on each limb. In the next 23 seconds, Serena grew up to 120 ft tall. Serena loved her new body. She grabbed Ash and gave him a 1 minute kiss.
