Sometimes or always, they want to change into different moods.
Sweet PersonalityThis personality resembles the 2012 sweet personality. It can be obtained by petting/rubbing your Furby Boom! a lot or shaking it for awhile. (Sounds like a strange method, but I've done the shaking method 3 times after getting the jolly personality and it worked each time.) This is also the default personality as well as pulling Furby Booms tail in the bath room within the app for Furby Boom!. She loves being petted, hugged, rubbed, backscratched and tickled, while she dislikes her tail getting pulled or being tilted, which will make her scared. She is represented as a calm Furby with flowers on her left ear, with hearts surrounding her.
To also turn her into this mode, you turn her upside down, hold her tongue and pull her tail for a few seconds, but if you have any progress it will be deleted (even the name you give to her). Her eyes have hearts on them, like the sweet 2012 Furby, but with round eyes and eyelashes Female personality.
This personality resembles the 2012 Chatterbox personality, saying things such as "We could like, eat a cow!" and "Oh No Ya Di'int!".This can be obtained by talking to him/her a lot or tickling him/her. This personality doesn't enjoy eating as much as other personalities, because she prefers to chat and dance. She also loves to shout and cheer. She is represented as a Furby Boom! creating a tornado with the words "Blah" around her. She has eyelashes like the 2012 Chatterbox personality. Female personality.
This personality can be obtained by playing a lot of music for him/her or pulling his/her tail. He resembles the 2012 Sassy personality. He enjoys listening to music but usually dislikes being petted, tickled, tilted upside down, or laying on his back. He often says "Dee-doh (translation: dude)" and will sometimes compliment others, and he will also fart and burp often. He is represented as a Furby Boom with a mohawk wearing sunglasses while playing on a guitar. Male personality.
The Jolly personality is obtained by overfeeding your Furby Boom!. He has either a Cockney or an Australian accent. He resembles the Crazy 2012 personality (both males). He enjoys eating quite a bit, along with burping, farting, petting and tickling. Some Jolly Furby Booms are fine with tilting, others are not. He gets scared quite easily. He also hates dancing (because he says dancing makes him sweaty), and will refuse to dance for more than a minute or two. He is represented by a fat Furby Boom lying down beside donuts and a soft drink. Some Furby collectors call it the "Fat Personality", because his favorite food is cake. Male personality.
Feisty PersonalityThis is the least common (or rare) personality yet. You can get this personality by tilting and shaking him/her a lot. She resembles a female version of the Viking/Evil 2012 personality.
As a more tomboyish Furby she hates being petted, hugged, tickled, and having her tail pulled. This personality often gets grumpy and always doesn't like being bored. She is represented as a Furby Boom! wearing a headband, with nunchucks while the words "BAM!" and "POW!" surround her. Female personality.
