Confirmed members[]
Unconfirmed members[]
Due to there currently only being one known confirmed member of this family and that members father, it is impossible to know what other characters may be a part of the family.
It seems likely that Birthday Cake could be a part of this family, due to them sharing a voice actor with Cake which is an aspect shared with all other families and their members.

Confirmed members[]
- Leafy
- Leafy's Family (unknown quantity)
Possible members[]
There is some possibility of Autumn Leaf being a part of the Leaf family, but there isn't enough information on how members of the Leaf family work to confirm that.
Unconfirmed members[]
Due to there currently only being one known confirmed member of this family, it is impossible to know what other characters may be a part of the family.
It is currently unclear what relation Evil Leafy has to this family, if any.
Tree family[]
The Tree family are a family that has been implied to exist, the implication being of at least more than 3 members existing and it consisting of siblings. Based on implication, this is the only family so far to have members of varying genders.
This family was mentioned in a very off-handed and joke-y way and was mentioned to refer to non-living instances of an object, so it is possible that this family actually doesn't exist.
Confirmed members[]
- Tree
- Tree's brothers and sisters (unknown quantity, debatable)
Possible members[]
There is some possibility of Spruce Tree being a part of the Tree family, but there isn't enough information on how members of the Tree family work to confirm that.

Due to there currently only being one known confirmed member of this family, it is impossible to know what other characters may be a part of the family.
Billiard family[]
The Billiard family has a confirmed member count of 3 known members although more are implied to exist, all of which seemingly being related to each other as siblings. Some members of this family have unconfirmed genders.
The canonicity of this family is ambiguous, as the post that mentions this family is incredibly joke-y in nature and the two theoretical members of the family have two different voice actors, which is unusual for families.
Confirmed members[]
- 8-Ball (ambiguous canon)
- 9-Ball (different voice actor) (ambiguous canon)
- 6783957285-Ball (non-canon)

Confirmed members[]
- Taco
- Taco's Family (unknown quantity, debatable)
Unconfirmed members[]
Due to there currently only being one known confirmed member of this family, it is impossible to know what other characters may be a part of the family.
Other possible families[]
Fire family[]
There is some possibility of a Fire family due to the 4 different fire characters. It is possible though that some or all of these characters have no relation to each other as this is all just speculation.
It should be noted that Firey and Firey Jr. have two different voice actors, which is unusual for families. In the BFDI x II 2024 Tour during the 3:30 screening at the Gerald W. Lynch Theatre, people have stated that someone confirmed that Firey and Firey Jr. have no relations. There is no source for this however, there is no existing proof within BFDI itself for this, and this does no exclude the possibility of relations regarding Fire-ette or Firey Jr. Jr..
Possible confirmed members[]
- Firey
- Fire-ette
- Firey Jr. (different voice actor)
- Firey Jr. Jr.
Due to being a machine, it's unclear if Firey Speaker Box would be counted within this theoretical family however one could consider him the "son" of Firey due to being created by him. Firey Speaker Box's Clone, being a clone of the original Firey Speaker Box, would be most similar to a sibling for the original Firey Speaker Box which would inadvertently make Firey Speaker Box's Clone be Firey's "son" as well.
Coin family[]
There is some possibility of a Coin family due to the 4 different coin characters. It is possible though that some or all of these characters have no relation to each other as this is all just speculation.
It should be noted that Coiny, Nickel, and Rusty Coin have three different voice actors, which is unusual for families.
Possible confirmed members[]
- Coiny
- Baby Coiny
- Nickel (different voice actor)
- Rusty Coin (different voice actor)
Sponge family[]
There is some possibility of a Sponge family due to the 2 different sponge characters. It is possible though that some or all of these characters have no relation to each other as this is all just speculation.
Possible confirmed members[]
Flower family[]
There is some possibility of a Flower family due to the 2 different flower characters. It is possible though that some or all of these characters have no relation to each other as this is all just speculation.
It should be noted that Flower and Rose have two different voice actors, which is unusual for families.
Possible confirmed members[]
Due to being a machine, it's unclear if Flower Speaker Box would be counted within this theoretical family however one could consider her the "daughter" of Flower due to being created by her. There is also Robot Flower, a robot designed after Flower by an unknown creator, but she wouldn't be part of this family unless adoption of some kind was involved or if the creator turned out to be someone from the theoretical Flower Family.
Tennis Ball family[]
There is some possibility of a Tennis Ball family due to the 2 different tennis ball characters. It is possible though that some or all of these characters have no relation to each other as this is all just speculation.
Possible confirmed members[]
Pencil family[]
There is some possibility of a Pencil family due to the 2 different pencil characters. It is possible though that some or all of these characters have no relation to each other as this is all just speculation.
Possible confirmed members[]
Wood family[]
There is some possibility of a Wood family due to the 2 different wood characters. It is possible though that some or all of these characters have no relation to each other as this is all just speculation.
Possible confirmed members[]
Rock family[]
There is some possibility of a Rock family due to the 2 different rock characters. It is possible though that some or all of these characters have no relation to each other as this is all just speculation.
Possible confirmed members[]
Marker family[]
There is some possibility of a Marker family due to the 2 different marker characters. It is possible though that some or all of these characters have no relation to each other as this is all just speculation.
Possible confirmed members[]
Block family[]
The possibility of a Block family could be possible if it turned out that Blocky or a theoretical other member of the family created Electric Blocky. It should be noted though that the nature of Electric Blocky's object and status as a mechanical mind is unknown.
Book family[]
There is some possibility of a Book family due to the 16,608+ different book characters. It is possible though that some or all of these characters have no relation to each other as this is all just speculation.
It should be noted that the Ten Words of Wisdom and Eleven Words of Wisdom contestants are currently not canon to the BFDI series, so even if there was some relation between these characters none of this would be canon.
Possible confirmed members[]
- Book
- All 491 TWOW contestants
- All 16,607 EWOW contestants (some part of the original 491)
In EWOW there are 100 AI contestants. These would have debatable claim to this theoretical family due to their robot nature.
