Hi, im sorry if this is old but at least i found it myself
Back to the thing, i found 5 different ways to win a Murloc costume that looks like this
For further instructions check Unofficial World of Warcraft Forums - Competition - Win a Murloc Costume! out. And BTW there is a level 1 race at 7pm for alliance and 8pm for horde on Turalyon (EU) the 13th December (Today) please join the race (Edit): You need to be a Gnome to join the Alliance Race, and a Undead to join the Horde race! The race start for horde is outside the ruins of Lordaeron and the alliance race starting place is at the gates of Ironforge, happy racing !
Sorry if this is already posted, and if not i guess im lucky
