Podori is the mascot for the Korean National Police Agency. He has been presented on Korea & Animation before. Here is what has been learned about him since then. 
This sticker was placed by the Seoul Police Department inside of a subway station. Look very closely at the lower right-hand corner and you'll see the signature of Lee Hyeon Se. Lee, often upheld as the most famous comic book artist in Korea, apparently designed Podori. Here are some close-ups, insights, and translations from that sticker: 
It appears Podori can patrol Seoul apartments by flying around with a Doraemon-like helicopter cap. Here he is observing how careless Seoul citizens are. Podori: Wow, they don't even bother identifying their guests before opening the door! Podori: Milk and newspapers are stacked up outside. They must have been gone for a long time.
Podori: They don't turn off the light while out at night!
Podori is a very respondent police officer.
Podori: Freeze!Crook: Oh! That was so fast!
Woman: Oh my! It's only 3 minutes after I reported this!
Podori isn't afraid to put troublemakers in their place. Angry Wife: Beat him! Spank him harder! Because he's an alcoholic! Upset Daughter: I hate my dad!
Sound Effects: Spank! Spank!
Watch out criminals, because Podori is watching you even more closely! Podori: Big ears to better hear citizens. Podori: Big eyes to better catch thieves with.
Crook: Argh! It's Podori!
And here's a treat. The other police mascot! Although, she isn't seen around as much as Podori. I wonder what her story is?
In case you didn't know, combining such cute characters with not so cute organizations, like the police department, softens that organizations image. Who would you rather have boss you around, a gruff looking police officer or little Podori? But don't be mistaken, Podori is the real deal. If you look closely you'll notice that his badge is not a mere drawing but a real badge!
I think there may be a problem with having Podori as a mascot. He may be too cute a character for the police department. It almost makes me want to commit a small crime just so I can see him. Then maybe I can give him a choco pie and he'll let me off the hook. Then we can go get pizza or something and we'll become close buds. Then we'll team up and become a crime fighting team!
I also noticed that Podori's design seems awfully similar to this character in Pata Pota Monta, a Japanese production. Maybe they are cousins? I prefer Podori, though. Especially in the first image. I particularly like the way his eyes are drawn.
