U can pick to have a tiny maia or giant maia. But their are rules :

- if u are gonna be sans , he is always giant , even when I'm tiny.

- when u have giant sans , u have to show him ripping cloths and he has to be growing , he cannot be always big , something has to happen to him
Ex - blue stuff was going thru his ribcage and he was growing , his clothes ripping.

- if u choose tiny maia , u have to be taller then her

- if u want to be giant , that's fine

- if giant maia , then u have to be in a lab.

- if u giant sans , he has to show him in pain
Ex - sans : it...hurts ! * groans and he clutched his stomach

K , here is giant maia -

This is tiny maia -

Giant Sans is the same but has rips in his clothes.

Have fun !
