For some reason, the unicorn's mannerisms remind me of the King of All Cosmos from Katamari Damacy. I have the sound off at work, so I don't know if he's speaking in scratches.<p>From a purely pragmatic standpoint, this 404 page isn't incredibly useful. It doesn't provide help on finding the page you were looking for, it doesn't link back to the homepage until you click alllll the way through, and it encourages the user to click the unicorn instead of interacting with the site in a more meaningful (and revenue-producing?) way. That said, for some companies style, image, branding, etc are worth a lot, so having this easter egg could be worth the cost. I'm not familiar enough with Blippy to judge.
