Continuity

Since people have been curious and asked me in the past, here's where I think every character exists. Canonicity isn't a very rigid thing on my end though, as I often have my characters cross over despite this:

Universe A: 

- Mippi

- Mop

- Siyan

- Georgina

- Cordi

Universe B:

- Brooke

- Fanny

- Elegance

- Auranne

- Bongley

- Mrs. Bongley

- Dizzette

- Jackie

- Penn Pusher

- Webbina

- Nel

Universe C (The one with the chibis):

- Mibby

- Mob

- Chibi Brooke

- Chibi Siyan

- Chibi Nel

Universe D

- Blimm (stylistically he doesn't fit in anywhere else, otherwise he'd be in Universe B)

Exists across multiple universes:

- Matras

- Classic (Blocky) Matras (same deal as the other Matras)

- Mister Nestor (exists in Universes A and C because both Mop and Mob have her as a pet)

- Stacky (she has been built in Universes A-D, as this gives me an excuse to pretty much use her wherever I want)
