Everyone is familiar with the endearing, humorous, and adorable nature of Furbies. Unlike their predecessors, Furby 2012 and Furby Boom exhibit multiple distinct personalities. The acquisition of these personalities is contingent upon your interaction with your Furby. The Evil personas are relatively uncommon but easily attainable. In the Furby 2012, they are referred to as 'Viking,' while in the Furby Boom, they are known as 'Feisty.'
Steps to Follow
Transforming Your Furby into a Menacing Companion

Place your Furby in front of you. If it hasn't been activated or awakened yet, proceed to do so. It's important to note that this method exclusively applies to your mixel. Attempting this on a Furby Boom (2013) will result in a Jolly Furby instead.

Place your finger inside your Furby's mouth and gently press down on its tongue. The quickest method to turn your Furby evil is by overfeeding it.

Move your finger around in your Furby's mouth for about a minute. This action will make your Furby believe it's receiving a continuous feed. Your Furby might express discomfort or protest, but keep going. Remember, overfeeding is the key to making your Furby evil.

Wait until your Furby begins acting erratically before removing your finger from its mouth. Your Furby will emit strange sounds, and its eyes will turn white. It will shake and behave unpredictably. After a short while, your Furby's eyes will assume an evil, slanted appearance.

Enjoy the antics of your evil Furby! It will exhibit grumpy behavior and may even snap at you if you attempt to pet it. If you wish to revert your Furby to its friendly state, try engaging in extensive conversation or playing music. Some individuals find this process may take up to 10 or 15 minutes. Alternatively, you can try petting it repeatedly; eventually, it will return to its pleasant demeanor.
