The youngest member of Little Lamplight, Bumble is six and the closest to a carefree child to be found in Little Lamplight. She's only just learned how to fire a gun but hasn't tried it out yet, because she literally doesn't have the strength to pull the trigger. She sometimes carries around a teddy bear that used to be her mother's and has been passed down through generations of Lamplighters. Lucy treats her like a little sister. She's also clumsy and prone to knocking into objects, which earned her nickname. She is extremely naive.
Bumble spends most of her time in the Schoolhouse either with Joseph (or, "Uncle Joseph" as she calls him), or with Lucy in the clinic.
Bumble is likely to be found at the schoolhouse building. If she is not there she sometimes can be found in the main cave.
Penny, when asked how she likes the classes in while in the schoolhouse, will say "It's great, but Bumble's always bugging Joseph when he is trying to teach me." then say "she's just jealous because she doesn't have a brother anymore." This suggests she did have a brother, but it is uncertain whether he left Little Lamplight for Big Town, was killed in the wastes, or just disappeared from Little Lamplight.
It is possible to keep Bumble as a follower for a short while. As soon as you exit Little Lamplight, open up your Pip-Boy and fast travel to your desired destination, instead of bringing her to the slaver. When arriving you will see that Bumble is still with you. She will not follow you into houses or anyplace that causes a loading screen. Upon returning outside, she will either have disappeared, or, in the case of walking through Megaton's gate, she will still be around, however she won't follow you anymore, and will walk back to Little Lamplight. She can be given a weapon, but she will never equip it and always runs away at the first sign of an enemy, and will not come back to follow you once they are gone, making her useful only as a packmule.
Although she is technically "enslavable" only the Child Slaver can really enslave her, not the player.
xbox360ps3 After Bumble is taken by the Child Slaver outside of Little Lamplight and the player speaks to Eulogy Jones to receive the Boogeyman's hood, it is possible to once again select the dialogue to lure a child out of Little Lamplight. Bumble will then reappear in Little Lamplight still wearing the slave collar and can be lured outside again to the Child Slaver. However, the dialog between the two will not unfold as it should and they will stand there indefinitely.
If you decide to kill all of the people at Paradise Falls to free the captured Little Lamplight characters you can still have Bumble go with the slaver if you previously talked to Eulogy about capturing the kids at Little Lamplight, but if you do you don't get a reward and the characters go inside the slave pen, into the slave room and disappear.
