I literally just realized I haven't posted ANY of my drawings of Mini!
Here's the official drawing of her:

Ignore my phone's shadow please.

Here's a height comparison:

She's so small, she can fit in Sans's hood and Papyrus's scarf.

Fun Fact: Death, Moon's HorrorTale oc, absolutely loves her and the au Minis.

Mini:
Acts young and childish and clueless, but is actually a lot older and very smart.

She was a failed experiment. She was supposed to be like how Flowey is, able to contain both a human and monster soul, but she can't absorb either of the two, because she is part human and part monster.

She's mute, so she uses a lot of movement to show what she's trying to say. She also has a pen and note pad in her pocket. Although, if she tries hard enough, she can say one or two words. (The monster side of her was melting, and the injection of JUSTICE saved her, in a way. So, some stuff is a little... melted.)

Sorry if this was more confusing than informing.
