The game strings hinting the party were first discovered in January 2016.[1] On February 3, 2016, Club Penguin Times brought an account of unexplained noises coming from underground. On the same day, Megg also published a blog post with anagrams of what could be expected on the party[2] and ClubHerbert.com was updated.
Plot
During the Operation: Crustacean, Herbert stole the UFO’s power source and then went hiding again. He re-apeared a week after the aliens left with his new invention, the Laser of Doom. In a short time, penguins managed to disable it starting a disco party in Forest. Herbert didn’t give up though and came up with the Shrink Ray of Doom. He managed to shrink Rookie but the second invention was also disabled soon. In the week 3 of the operation, Herbert emerged with his latest invention, the Uncolorizer of Doom, hoping that “Penguins won’t want to stay on a colorless island!” He was mistaken, however, and after exploring the hole in the ground and waddling through an underground maze, EPF recovered the meteor of the power source and Herbert was defeated.[3]
