Solution:

1. Just a little trick about variable.
2. View page source code, and find the javascript code below.
   
   <script language="Javascript"> RawrRawr = "moo"; function check(x) { "+RawrRawr+" == "hack_this_site" if (x == ""+RawrRawr+"") { alert("Rawr! win!"); window.location = "../../../missions/javascript/4/?lvl_password="+x; } else { alert("Rawr, nope, try again!"); } } </script>
   
3. The value of variable "RawrRawr" is "moo".
4. The IF statement is the hint.

   if (x == ""+RawrRawr+"")

5. "" is equal to NULL, i.e., nothing. So, the answer is "moo"
6. Input "moo" and submit. It's done!
