I read the whole list, and didn't see any real coherence. I kinda hoped the "named" cuddles would all have something to do with Perl/OS/Editor/Distribution/Whatever on-topic relation that matches, so a Camel/Dromedary would match Perl, a Lizard might be from SUSE, a devil to Debian, and several other IT related stuffed ones could probably be surfaced.

I've never seen a penguin as a bird, as it cannot fly. I know several other (extinct) birds cannot/could not fly either (dodo, emu, ostrich), but the penguin deserved a spot in this list far more than a few other entries to my honest opinion.
