Use the scenario 'Santa's Little Helper' under the Official Scenarios group. Gene sequencing does not matter. Difficulty does not matter, though I recommend casual. Starting country does not matter. As soon as you can, evolve the following symptoms, while devolving any mutated symptoms.
Santa's Little Neurax Worm
Festive Tendrils
Sloth
Gluttony
Jealousy
Indulgence
Partying
Intoxication
Once you evolve Intoxication, devolve Partying and Indulgence. Continue to devolve any symptoms that mutate, and evolve the following abilities:
Gift Plane
Present Parachute
Chimney Shoot
Red-Suited Pilot
Shortly after all of these symptoms and abilities are evolved, you will get a popup stating that humanity is on the naughty list
, and the achievement will unlock.
Lumps of coal all round!
