What on Earth is a “Fridge Dweller”?

Well, the background to this blog's name is simple: I am a big fan of the Neon Genesis Evangelion character Pen Pen.

Pen Pen, or Pen² (ペンペン) is a "hot spring penguin" and Misato's pet. He lives in a custom refrigerator in Misato's apartment, enjoys taking warm baths, eating whatever food he can get, and going to hot springs. He also appears to have a relatively high degree of intelligence, as he is also shown watching TV and reading newspapers … In the manga, he is the result of a genetics experiment at Misato's former workplace, and she adopted him after the experiment's conclusion rather than let him be euthanised. His wingtips have retractable claws, which normal birds do not have.
