A new boss: An artist or EXP-012
The artist, an artist, also known as EXP-012, is a boss specializing in "art".
There are multiple attacks she can perform: a swipe, a dash, etc. She has a vulnerability window where you can hit her. Normal attacks won't work unless she's reloading.
She has lore, but it's your job to find it.
The crafting recipe requires bio-mass, latex base, an orange, a totem of undying, the palette (craftable), a flask of tears (found in the EXP-012 room) and three paper.

The reward for winning against her is the next feature.
Custom latex color and texture editing
Lets the player customize further custom latex, changing its color and texture.
To do this, you must have EXP-012's paint brush.
New blocks, food and medicine
The blocks include the ice cream block, the SCP-009 crystals, an orange bucket and headphones.
The food is the ice cream cone, found in the cafeteria.
The medicine helps against pale, the crafting recipe must be found by you.
