Farkle was getting good at the "hold the biscuit on the nose but don't eat it" trick. But Master started asking him to stand up on his hind legs, then balance it with his forepaws, then pick it up off his nose and eat it like a human eats a carrot.
Sheesh! A corgi wants to please his master, but this was getting ridiculous!
"Well, there's no getting around it", thought Farkle. "I'll have to physically transform myself in order to make master happy."
