"We will not have giant rats running around the farm," says Mrs. Crumpet.
"Giant rodents. You see, they're really just giant guinea pigs."
"Well, people do keep pigs as pets," adds Orange Bear.
"That's right, Orange Bear," smiles Mr. Crumpet. "And these critters are so docile, they'd make even better pets than pigs. Come to think of it, they're really more like dogs."
"Can they be house-trained?" asks Mrs. Crumpet.
"The capybara craze is gonna sweep the nation, and we'll be right there on the ground floor!"
Orange Bear whispers into Mrs. Crumpet's ear. "I told him the pet rock's already been done. Sea monkeys, too."

These creatures somewhat resemble the Nutria that have invaded my local golf course. I threw a golf ball at the giant rodent creatch and it did not subside from its herbivorous feeding frenzy.
However, these Capybara characters do not look as nefarious as the Nutria. Is it because of their largess? Or the absence of the rat tail? Something about the rat tail that is disturbing. I never understood this fashion statement either. Who would want to look like a rat?
I wonder if they would get along with my cat?
