Non chronologically sequential snippet. Enjoy.
"Isn't this great, coach? We're having an adventure together! After all this time!"
"Y-Yeah. Like, I hope there are less lethal dangers, this time around. Zoinks!" What had started as a visit to an old classmate had turned into yet another monster hunt, one with a real monster this time. Computer generated, to boot. Scooby agreed with a low whine, but there was no spoiling Winnie's mood.
There she was with her coach, all alone since with there being six of them (she had managed to persuade them to let her help) they had split up in couples to cover more ground, trying to solve a mystery and catch a baddy. Life. Was. Good. Now if she could only lure him to a secluded place... She clenched her fists, grinning as she currently had her back to him. It was the perfect plan.
"By the way, like, how did you... Well, change, Winnie?" She turned around again, the skirt of her sundress flowing as she spun. "Like, I almost didn't recognize you."
"Hehehe... Seems like Werewolves can shapeshift, Coach. I just didn't know how to do it yet, at that age. Also, it's not like I had any reason to. We were all Ghouls and you didn't mind us at all... Well, after the first impression." She chuckled as she remembered the game of tag on the first day of school. Then she snapped her fingers. "I know! What about this?"
"Huh?" Under Shaggy's eyes, Winnie's body began to change. Her skin became darker, her hair became wilder, of a darker shade of red and her sideburns longer. Finally her ears and canines became elongated and pointed. "... Wow. That's like, convenient." He then smiled as he understood. "But yeah, you look a lot more familiar to me like this."
"Then, I'll stay like this all the time I'm with you, Coach." Winnie grinned and with a skip leaned her head against his right shoulder. Shaggy chuckled and then went to pat her on the head. Now, this? A normal werewolf would have gone ballistic at being treated like a dog, but had she had a tail, it would have been swinging.
"Nice thought but, like, try to stay shaved around my friends, alright?" He said and that confused her. She moved her head as to stare right in his eyes from below.
"Why is that, Coach? You don't trust your friends?"
"I do. It's just... They can't really keep a secret, you know?" Shaggy sighed. That was what started the whole Mystery Inc. gig, after all. While Shaggy would have been happy not to deal with monsters, ghost, aliens and similaria for the rest of his life, even if they were fake most of the times, Fred, Velma and Daphne were just too damn curious. They felt at their best when finding out the trick behind the latest monster of the day and if by chance the monster became real, they just couldn't resist trying to observe and study. The things behind, that's what they wanted.
But the problem was that they weren't exactly shy when it came to share their knowledge with the rest of the world. Fred and Daphne reveled in the attention -they created a TV-Show out of solving mysteries- and Velma was a firmly believer that the truth was made to be exposed, no matter what it was about. "So, keep the transformations to a minimum."
"Hmm... You sure?" She teased, crossing her arms behind her back and standing on the points of her feet, showing that the transformation had increased her height and a certain circumference.
"Yes, I am. This no joke, Win." Shaggy didn't seem to notice. For once, he was focused on the subject at hand. Winnie blinked and flushed, embarrassed as she bowed her head and went back to her human shape.
"Ok, Coach. Sorry." Shaggy smiled and patted her head one more time, to which she immediately brightned up.
"That's a good girl. Now let's keep... Looking for that... Virus." Shaggy swallowed as he started looking around again while Winnie was still lost in the bliss of petting and being called a good girl. Then she suddenly grinned to herself.
'Yes,I'm a good girl, coach. But wait till I'm alone with you somewhere secluded, like that nice inoperative lab in the right, and you'll see just how much of a bad girl I can also be... Yes, and bad girls need to be punished, to owl...'
"Aaaaaah!"
"Yes, just l-Wait a minute. I don't sound like that." She broke out of her reverie to find a terrorized Shaggy staring down a bluish humanoid... Thing. She frowned and snapped her fingers. "I was THIS close."
