Why Did He Turn Blue and Lose His Ears?

Hello! The reason why Doraemon is blue and earless actually stems from a rather heartbreaking yet absurd backstory. Let me walk you through it, and you'll understand.

The Beginning: Doraemon Wasn't Originally Blue

You might not know this, but when Doraemon first left the factory, he was actually yellow with two pointy, adorable cat ears. His appearance back then was quite different from the iconic look we recognize today.

The Turning Point: Two "Accidents" That Changed Him Forever

His transformation into his current form resulted from two devastating incidents that happened in succession.

First Accident: Ears Bitten Off by a Mouse

This marked the beginning of the "tragedy."

One day, while Doraemon was napping, a robotic mouse—mistaking his ears for cheese—chewed them off.

After being rushed to the robot hospital, despite receiving treatment, his ears couldn't be saved and were completely removed by the doctors. That's why he now has a round, earless head.

Fun fact: This terrifying experience left him with severe musophobia (fear of mice). Even the sight of a mouse makes him jump in fright or even shut down completely.

Second Accident: Cried So Hard He Turned Blue

Losing his ears left Doraemon deeply depressed. His girlfriend (a cat robot named Doramiko) couldn't help but laugh at his bald head, making him even more heartbroken.

Trying to cheer himself up, he decided to drink a bottle of "Spirit Potion" (think of it as a "happy potion"). In his panic, however, he grabbed the wrong bottle and drank a "Tragedy Potion" (a "sadness potion") instead.

This made things worse. After drinking it, overwhelming sorrow hit him, and he cried uncontrollably for three days and three nights.

Something remarkable happened:

Color Change: His tears washed away the yellow paint coating his body, revealing the blue primer underneath. So, he cried himself from a "yellow chubby bot" into a "blue chubby bot."
Voice Change: Crying for so long made his voice hoarse, resulting in the unique, slightly raspy voice we now recognize as Doraemon's.

To Summarize the Whole Story

So, here’s the sequence of events:

Originally yellow with ears.
Ears chewed off by a robotic mouse during a nap.
Fell into deep sadness after losing his ears.
Intended to drink a "happy potion" but accidentally consumed a "sadness potion".
Cried for three days and nights; tears washed off the yellow paint, revealing the blue base.
Ultimately became the earless, blue, hoarse-voiced Doraemon we know today.

So, behind Doraemon's adorable blue appearance lies this heartwarming yet slightly comical "accident." Now you know!
