But Slime from Dragon Quest sure looks like that car.
Crexian's photo was retweeted over 28,000 times.
However... here's a side view.
That is actually "Pichon-kun", a character from Osaka-based company Daikin. The character represents a drop of moisture, because Daikin's air conditioners won't dry out your house.
There is a whole fleet of cars, it seems. These cars are actually customised Toyota iQs.
Besides the blue Pichon-kun automobiles, there are pink ones.
And somebody spotted a brown one. This doesn't look like a Dragon Quest Slime. It's a turd on wheels.
