I’ve found these flash files on the web a year ago. Does anyone know where these characters come from or are derived from? Is this something big like Domo-Kun?
I’ll give a few cites.

Your links aren’t links.
There’s a Japanese message board called Mona, whose inhabitants seem to make a lot of these (the word “Mona”, either in English or Japanese, pops up a lot in the animations), and the cat seems to be their mascot.
Do a google search for “chinko momimomi”, but don’t view it at work!
