Is the title a reference to Chū Chū Lovely Muni Muni Mura Mura Purin Purin Boron Nururu Rerorero by Maximum the Hormone?

Maybe coincidentally the same idea with the sound effects.

By far, one of the most enjoyable comedy touhou doujin I have read xd

The lesson here is that mice are scary and must never be pissed off.
