As Grandma slowly drives her motorcycle through Townsville Park her gaze presently falls on three familiar looking boys, who are merrily kicking a volleyball to each other. "Say," a very intrigued Grandma inquires. "Who might they be?"

"Oh, why, they're the Rowdyruff Boys." Bubbles replies.

"They look so very much like you," Grandma remarks. "Might they be superheroes as well?"

"Uhm, well, yes, sort of," Blossom replies. "They're some boys we lo-I mean boys we know." The pink Powerpuff's face turns bright red as she says this.

"Do you like these boys?" Grandma inquires curiously.

"W-wh-what?" Buttercup stammers nervously. "W-well, we certainly do lo-uhm, uh...like them." Her face hen turns bright red as well.

"Well, they certainly do seem very sweet." Grandma replies. "Perhaps we should say hello."

"W-wait, please, Grandma-" Blossom replies urgently, but her warning comes a bit too late.

"Hello, boys!" Grandma calls cheerfully, giving the Rowdyruffs a merry wave. "How are you doing on this fine day?"

"Huh?" Hearing the call, the boys stop playing and whip around. "It's the Powerpuff Girls!" Brick whispers loudly with concern. "But who's that lady with them?" Butch whispers in reply. Boomer, however, not having a very clear idea of what he wasn't supposed to do, waves back with a big, cheerful, "Howdy, Miss!"

"Why, hello, dears!" Grandma replies.

"So, what brings you to our little corner of the world, miss?" Boomer inquires.

"Well, my granddaughters and I were just taking a little ride around the park and wanted to say hello."

"Ooh, how very nice!" the blue Rowdyruff replies with intrigue. Just then, he feels his brothers tapping him on the shoulder. "Uhm, bro?" Brick says. "Can we take a moment?"

"Sure thing!" Boomer replies, upon which he and his brothers quickly step to the side and huddle. "Boomer, what are you doing?" Brick whispers. "They're our enemies!"

"Imagine if the other villains had been walking by right at this very moment," Butch adds. "They'd never let us live it down!"

A perplexed look crosses the blue Rowdyruff's face. "But guys, don't we like them?"

"Like them? LIKE them?!" Brick echoes indignantly. "Whatever gave you a goofy idea like that?!" Boomer can't help but notice a blush crossing his brother's face at this very moment. "Well, for one thing, you're blushing." he replies.

"Buh-blushing?" the red Rowdyruff stammers. "O-oh no! It must have been from the candy I ate earlier!" He dramatically clutches his belly. "Boomer, didn't you read the ingredients?"

"But...Butch is blushing, too." Boomer replies.

"R-really?" the green Rowdyruff replies. "Oh no, I must be getting sunburned!" He lifts his hand to his face. "Boomer, why didn't you bring sunblock?"

"Oh, ho, ho, silly dears!" Grandma laughs warmly. "You can't walk away from love!"

"LOVE?!" the boys exclaim in shock. Brick turns casually to Grandma. "Y-you must be mistaken, miss," he says. "We barely even...like the girls."

"Oh sweetie, there's simply no need to deny it," Grandma replies. "In fact," A thoughtful look crosses her face. "Would you boys care to join us on our little sojourn about town?" Brick and Butch are ready to protest until Boomer quickly pipes up, "Yes, please!"

Boomer's brothers shoot disdainful glares at him. "Boomer are you crazy?!" Butch glowers. "If the other villains see us we'll REALLY never hear the end of it!"

"But she seems so nice," Boomer replies. "And honestly, a ride on a motorcycle might be pretty sweet!"

"Well...okay." Butch replies grudgingly. "With any luck we won't meet up with anyone we know."

No sooner do they make their way toward the motorcycle, however, when the ground suddenly begins violently shaking. "Buh-buh-buh-bro, what's happening?!" Butch exclaims. "S-s-stop moving! You're gonna make me fall! Bad underground! Bad, bad underground!" Boomer exclaims quaveringly.

At this moment, a humongous slug beast bursts through the ground. He's a large grey slug creature with reddish-orange eyes, a green, iguana-like spine down his back, and a gaping mouth, full of razor-sharp teeth(1). "Wow...ohmigosh!" the boys exclaim.

A determined look crosses Blossom's face. "Come on, girls, let's give this monster what for!" Upon this, she and her sisters begin to fly off. "You heard 'em, guys, let's get 'im!" Brick exclaims, upon which he and his brothers quickly fly off, too.

Concerned, Bubbles peeks over her shoulder. "Wait, you guys, we can't leave Grandma behind!"

"Don't worry, dear," Grandma replies consolingly. "I'll be very safe right here. Now, please run along and fight the horrible slimy monster!" Boomer gives a very audible gulp. "Uhm, sure thing."

(1) The slug monster resembles the one Buttercup battled in the monster simulator in the episode, "Bubblevicious."
