Moorie

Marie seemed like a good pick to Chie considering she was the only girl chie was friends with that she hadn't changed in any way. Making her the prime candidate

"What to do with her though?" Chie thought. Maybe something to do with the weather? No, she couldn't think of anything related to that. What about her poems? Maybe something to do with writing or speaking?

Then inspiration hit her! Taking out the book, she wrote in some humiliating changes to the velvet room girl.

Marie can only speak and write in moo's. With enough effort, someone can make out what she's mostly trying to say.

When angered, a handful of grass can calm Marie down. Eating some will make her dumb and docile for a while.

It didn't take long for Chie to see the fruits of her labour when a loud moo came from behind her. It was Maria, who was pissed off at something or maybe someone? All Chie could piece out was that it had something to do with her poem.

"Moo! moomoo moo! moomoomoomomo!" Marie continued to shout, getting up close and personal with Chie. Deciding she had had enough of this. She grabbed a handful of grass and gave it to the angry cowgirl.

Maria's attitude quickly began to change as her eyes slowly glazed over and her chewing changed to grazing. Her moos became less frequent and more akin to a natural sound.
