Duran-kun and Kiyo-chan's Omake Theater!
(featuring the Tokiha-Okuzaki family pet)
Once upon a time, a scorpion approached a frog sitting by the bank of a stream.
"Excuse me, Mr. Frog," it said, "but I need to get to the other side of the stream. Could you carry me on your back as you swim across?"
"But Mr. Scorpion," the frog replied nervously, "if I let you on my back, you will sting me with your poisonous tail."
This was not an unreasonable fear, for most animals do not like to let poisonous creatures crawl on their backs. But the scorpion was not deterred.
"Mr. Frog, if I were to sting you in the middle of the stream, and you died, then I would drown. Surely I would not do such a foolish thing."
The frog thought about this for a while, and decided that it was logical.
"All right, then. Get on my back, and I will take you across the stream."
The frog hopped into the water, the scorpion jumped onto his back, and they set off swimming. But sure enough, in accordance with its nature, when they were about halfway across the river, the scorpion viciously stabbed its stinger at the frog's unprotected back.
The frog, quite offended by this antisocial behavior, bucked the scorpion off into the water, then zapped it with his tongue and ate it, scorpion apparently tasting something like lobster, only spicier. He then continued on his way across the stream, where his owner was waiting for him.
"What kind of idiot scorpion tries to sting a metal frog?" Akira groused, picking up Gennai. "And now I need to touch up the scratch in your paint job, too."
"Ribbit."
