An apocalyptic creature from the twelfth veignesia of Azaroth. It is prophesied that Lileej (or perhaps written Lile~ej in the time of the skydrawgeths) will bring destruction and sadness to all in it's path. However, the day of it's coming is unknown...
The Lileej is defeatable however...with the use of a huggle monster engagement, maneouvered to perfection with a full heart.
Because of the uncertainity of the actual existance of the creature or whether it is an ancient myth, it has become a sort of insult.
'You're such a lileej, you know that?'
'Don't throw that chihuahua saber at me you walrus-esque lileej!'
