A/N: I have no idea if anyone else has seen this, but I've seen under DM's eyepatch! If you watch the Four Tasks of Danger Mouse, get to the part about the witches' broom, and watch until he lassoes it, then pause before he gets whisked round the room by the broom. If you're quick, his eyepatch is shown to be off his face, exposing his left eye- and it is how I describe it in this oneshot! I saw it! I have a screenshot of it on my Kindle Fire.

Reviews are welcomed, and I will understand if people resent me for finding and exposing the truth under our hero's eyepatch. Please feel free to read on!

In a perpendicularly perfect pillar box on the corner of Baker Street, Danger Mouse and Penfold were tucking into breakfast one Thursday morning.

Danger Mouse grimaced as he attempted to eat his hard-boiled egg; and not because the spoon had been ruined (again) in the attempt due to Penfold accidentally overcooking the eggs for the 150th morning now.

No, it was more that his eyepatch was exceptionally stiff.

"I say, Penfold, you've starched this eyepatch too much!" The mouse complained.

"I'm sorry Chief." Penfold answered sheepishly.

DM wanted to take it off for even a moment and relieve his irritated eye- but he was reluctant to let his best friend see his bad eye underneath. So, when Penfold wasn't looking at him, he accidentally on purpose knocked a knife off the kitchen table.

"Oh dear, what a butterfingers I am!" He said, trying to sound embarrassed.

"More like butter-elbows, sir," Penfold replied, chuckling at his poorly made joke. Danger Mouse rolled his eye.

"Ha, ha- how very funny Penfold." Danger Mouse replied sarcastically. Now, would you be so kind as to pick it up for me, please?"

Penfold frowned. This sounded too trivial a request for Danger Mouse to ask of him; but he hated being on the receiving end of the mouse's foul temper, so he merely said nothing and obediently went to grab it.

At once, Danger Mouse shifted his eyepatch from his left eye and rubbed at the surrounding area gingerly, feeling the relief seep into his skin.

...

Penfold, meanwhile, had retrieved the knife and was just about to rise again when a reflection in the blade caught his eye. It looked like... a black dot on white, before the black disappeared into a cloud of white.

But what could it be? He wondered. He looked up curiously, pondering on what that strange dot was.

He merely shrugged and put the knife on the table beside Danger Mouse's plate before sitting back in his own space again.

"Thank you, Penfold." DM said politely, hand covering his left eye. "Listen, could you do me another favour and get me a new eyepatch please, old chap? This one is a tad uncomfortable."

"Of course, sir," Penfold replied, and took DM's eyepatch away with him. The mouse sighed and allowed his left eye a chance for some air.

Oh gosh, how he resented it! It was an ugly thing- a tiny black dot, almost like a perpendicular hole, on his face.

He had been born with only one eye. His mother, a famous and celebrated female spy, gave birth to him climbing up Mount Everest, and he successfully completed the hike hours after.

When he was taken back to England, he was diagnosed with anophthalmia; though he never learned this until he was older- about six years old, when his mother sat him down and explained the reason for the absence of his left eye.

Due to this horrifying condition, he had no choice but to wear an eyepatch. Anyone who found the truth behind this teased him mercilessly, and made him feel like a freak who didn't deserve to have friends.

Some were more understanding, but they were never allowed to see under his eyepatch, for personal reasons. Heck, even Colonel K had only seen his lack of a left eye briefly due to a medical examination.

"Here you are, sir- a fresh new eyepatch for your left"-

Danger Mouse jumped out of his skin as he heard Penfold's voice address him. Jolting back into reality, he realised with horror and dismay that he had forgotten to cover his left eye with his paw.

His missing eye was laid bare for Penfold to see.
