The Trio of multidimensional chaos (Two out of the three at least). The three very close Best friends (I really like how I redesigned Mayflower)

------

Edit: I'm adding this in so that you can get to know these fanchildren better since it'll take forever to do their profiles and finish them)

Sapphire is Monty's daughter, her mother and him are divorced (she didn't take it very well)

Mayflower is Spinel and Connie's child (but since I ship Steven, Connie and Spinel together she's also Steven's kid)

Pinecone should be kinda obvious by the name (she's a billdip fanchild)

----

Sapphire is the oldest (being 16 years old)

Mayflower is the second oldest (being 15 years old)

and Pinecone is the youngest (being 13 years old)

----

They all do a lot of things together when they're able to

Despite all having very different personalities (Sapphire is very emo, Mayflower is sweet and optimistic, and Pinecone is flat out Chaotic neutral), they all get along very well and don't argue that often

Pinecone causes the most trouble since she's half demon of course

Sapphire wants to be like her great grandpa Rick but he chooses to ignore her wishes (So she steals things from him often)

They all have been to many dimensions thanks to Pinecone's portal making ability and Sapphire sometimes stealing Rick's portal gun

Mayflower tries her best to prevent those two from getting into more trouble (doesn't usually succeed though)
