Animal Hospital (Anomaly) Updates
The verified changelog, newest first. Updates run on a bi-weekly schedule; after each one, affected guides are re-checked.
Latest update — 2026-09-05 · Second Floor
The Second Floor expansion went live September 5–7, 2026: a new upper floor with the Laboratory, the DNA Sampler tool, pink and green serums, six new skins, Journal achievements and the Squiggles NPC. The Lab unlocks after your first ambulance visit (or instantly with Fast Start).
The Lab is a separate system: serums are experimental effects and do not replace the normal patient remedies in Rooms 1–8 — see the Treatments page. Vial recipes, ingredient-to-DNA mapping and exact Lab mechanics are still being edited by the community and are patch-sensitive; we do not publish a recipe list until it is current-game verified.
