RedHood123 suggested the Woodland Critters battle today's boss. So, here you go.

"This place has gone to shit." Sighed Ryuji. "Mutant hamsters?"

"It could've been worse." Plucky replied. "They could've made statues of me, then destroyed it."

Suddenly, some of Hamister's minions made a giant gold statue of Plucky, then blew it up.

"Looks like that happened, Plucky." Hamton informed.

Suddenly, Raccoony found a book on the floor. The book was "Cool Cat Stops Bullying."

"Hey Raccoony, what book have you got there?" Beavery asked. "Cool Cat Stops Bullying?"

"I don't know where it came from." Raccoony explained. "It was just laying there."

Suddenly, Cool Cat jumped out of the book.

"Hi everybody!" He greeted.

The critters screamed.

"Ooh, new animal friends!" Cool Cat exclaimed.

Derek Savage approached the group.

"Yeah, it looks like Cool Cat made new friends." He said.

"New friends?" Beary asked.

"Yeah, you don't wanna be a bully, do ya?" Derek asked. "Cool Cat, let's show them what we think of bullies."

Derek Savage pulled out a plain writing book, and wrote something in it. Suddenly, Cool Cat turned savage, with sharp teeth and claws.

"Attack the bullies!" Derek exclaimed.

Cool Cat sprang at the critters with ferocity.

"Duck!" Deery exclaimed.

"Everyone, there's only one thing we can do." Porcupiney informed. "You all know what to do!"

All of the critter's eyes turned red, and Cool Cat's tail caught on fire, then a two headed Cerberus appeared.

"Wait, the book!" Mousey exclaimed. "We need to get the book away from Derek!"

"Daddy Derek will protect me from the bullies!" Cool Cat exclaimed.

"Say, I just realised something!" Raccoony exclaimed. "In the books, Cool Cat's parents are both cats! But here, Derek is a human!"

"So, you learned the truth." Derek informed. "That's right, I wrote Cool Cat's original dad out of existence and took over! My intention was to add rumours about it to gain more popularity."

Little did Derek know that Cool Cat could hear him.

"My... dad?" He said. "You're not really my dad!"

Cool Cat attacked Derek, causing him to drop the book. Squirrely grabbed it, and began writing stuff.

"Hey, what are you writing?!" Derek demanded.

Suddenly, Derek had springy legs, and bounces away into the distance.

"I can't believe it." Cool Cat sighed. "All those times were a lie."

"Cheer up." Foxy informed. "He got his just desserts."

"Yeah." Rabbity agreed. "You won't have to worry about him anymore."

I know this chapter was short, but no matter.
