Katie decided to open the book to the first page. She started to read the page. It explained the book to her.
It started off saying each page had one picture on it. Under each picture there were two words. Then it said reading the page would cause a transformation.
If the reader were to read the words, they would become dressed or in a costume like the one on the page. If anyone was in the room when the page was read, they would become that thing on the page.
On the bottom of the page there were two words. The words were 'changus backus'. It said to read this to change back to normal. However, if someone changed with you, they have to be in the room too. If they aren't, they will be trapped in their form. Katie said this to Tiffany.
Tiff said, "Lets try it."
"You sure?" Katie asked.
"Yeah! Pick a random page, and lets try that one," Tiffany said.
Katie opened the book to a random page. The picture was a girl dressed in a very juvenile attire. It looked like the girl was wearing a diaper and a onesie. She also had pigtails and a pacifier.
"Are you sure you want to try this one?" Katie asked. She showed he picture to Tiffany.
Tiffany nodded. "It should be a good enough change.
Katie looked at the words. It said Toddlerus Changus. Katie said that out loud.
Then her clothes changed. Her underwear became a thick diaper. The diaper actually felt comfy. it pushed her legs apart. She was wearing a large onesie. Her hair was in pigtails. She was sucking on a pacifier.
Katie looked over at Tiffany, and her eyes got wide. There wasn't her friend anymore, there was just a two or three year old girl. The little girl had her hair in pigtails. The little girl had on a pink onesie too. Inside the onesie a diaper could be seen. The little girl had a pacifier in her mouth too.
"Tiff is that you?" Katie asked.
The little girl said "Yes, it is me."
"Wow, it worked," Katie exclaimed.
"Yeah, but now what should we do?" Tiffany asked sounding way too mature for her smaller body.
Katie thought for a bit. Then...
