Nothing

The secret easter egg site, secret.axolotlia.com has a TON of hidden stuff, if you still cant find out how to do it, it is simple:

Take the first letter of each word on the 3 visible pages.

Let's say a page Squilliam existed, and it read "Squilliam's armpit needed deodorant." You would take the first letters and get "sand". One of the three pages holds the key to the rest of the site.

There are a LOT of hidden pages you get that way.

When you get there the page links explain what type of page you're on. /e/ is an easter eggs often with secrets, one of the originals. /j/ are joke pages, newer and with no hidden meanings. /f/ are pages I got from the future.
