The Eco-friendly Frog not only boasted a patch of green atop its head that looked environmentally friendly, but it also practiced environmental concepts by setting an example.
Every time this little frog went out, it neither stole nor robbed, it just picked up trash that others had discarded.
According to Hephaestus, it operated randomly within a three thousand square kilometer area centered around its master's mark.
Simply looking at the numbers, many people might not grasp the concept of three thousand square kilometers.
Let's put it into perspective with a few examples. According to Baidu Baike, the area of Hebi City is 2140 square kilometers, Jiaozuo is 3972 square kilometers, and Shanghai is 6340 square kilometers.
The three thousand square kilometers lay right between Hebi and Jiaozuo, about half the size of Shanghai, so it's quite a large area and the trash it could bring back was purely by luck.
