Acting quickly Captain Underpants put George, Harold, Double D, and Eddy on his back, and grabbed Ed. Captain Underpants flew upwards until he got to the forcefield.
The zombie nerds jumped upwards, with Captain Underpants barely dodging them.
"Not good not good," said Double D. "How can we fight against giants and win?"
"I could fight them," said Captain Underpants. "But they appear to be too fast, and there are too many of them."
"Maybe you could grow in size," said Ed. "I've seen superheroes it on television."
"Captain Underpants is not that kind of superhero moron," said Eddy.
"Actually we have something that could work," said Harold.
George took out a small device.
"This is the Goosy-Grow 4000," said George. "We can use it to make Captain Underpants grow in size."
"And don't worry we can use the Shrinky-Pig 2000 to return him to normal size."
"I heard of those," Double D said in amazement. "They were invented by Professor Poopypants.
Ed and Eddy laughed loudly with laughter.
"That's not funny," said Double D. "Professor Poopypants was a brilliant New Swisslandian scientist who could have solved the world's problem, but he went insane."
George and Harold did not mention what happened in their fourth book.
"Can I grow big too," said Ed. "I want to help save the world."
"Sure Ed," said Captain Underpants.
"In the meantime," said Eddy. "Me, Double D, George, and Harold can defeat those aliens."
"That's noble of you," said Double D.
"I guess you're not as bad as we thought," said George.
"You may have been a jerk but you're willing to help save the world," said Harold.
"I may be greedy, but I can't just let the world end," said Eddy. "Plus, people like heroes."
"Ready when you are Ed," said Captain Underpants.
"Ready," said Ed.
George blasted Captain Underpants and Ed with the Goosy-Grow 4000 several times, causing Ed and Captain Underpants to grow.
