I don't own WordGirl or the Powerpuff Girls.
Once Bubbles met up with WordGirl and her sister, they flew to the grocery store and found Captain Huggy Face tangled in string cheese and WordGirl holding the part of the mousetrap metal so it would not trap her.
"Stop right there Dr. Two-Brains? Is that his name?" Blossom asked Buttercup and Bubbles. They shrugged.
"Yes," WordGirl answered.
"N—who are you three?" Dr. Two-Brains said as he turned around and saw three small girls flying in mid-air.
"So he is a mouse," Bubbles said.
"Who are you?" Dr. Two-Brains asked them.
"The Powerpuff Girls," Buttercup said as she put her hands on her hips. "I'm Buttercup."
"I'm Blossom."
"And I'm Bubbles."
"Brilliant," Dr. Two-Brains said as he threw his hands up in the air, "one of you will be my experiment. The cutest one."
"Who does this guy remind me of somebody?" Buttercup asked.
"Are you referring to Mojo Jojo?" Blossom asked.
"Maybe," Buttercup shrugged, "they're both scientists."
"Yeah but they are different," Bubbles said, "one of them is a monkey scientist and the other is a mouse," Bubbles said.
"Thanks Bubbles it was really hard for me to figure it out," Buttercup said sarcastically.
"You're welcome."
"I can't believe that some of the villains from this town have a lot in common with our villains back home," Blossom said.
"Pretty weird right," Buttercup said.
"Hello!" Dr. Two-Brains said as he got their attention, "are you going to battle with me or not?"
"Yes," the three of them said as they flew towards him.
In a swift movement Dr. Two-Brains pulled out a sleeping spray. "Nighty, night," he said as he sprayed it on their faces and the three of them collapsed on the floor.
"Stop it!" WordGirl yelled at him. Dr. Two-Brains sprayed the sleeping spray around the store making WordGirl fall on the mousetrap with the metal part trapping her there. The spray also affected Huggy for he fell asleep too. Dr. two-Brains took the cheese from the shelves and he also took Bubbles along with him so his experiment could be completed.
