Tendril

Behavior

A massive purple blob with protruding tentacles that can only spawn after completing a surgery in Room 8. While a patient is recovering from surgery there, there is a chance they will say they feel strange and the Tendril appears, starting a timed 'Monster Emerging' emergency event. It does not harm the player directly but will kill the patient (recorded as an animal death) if the timer runs out. Starting the surgery again does not reset the timer to 45 seconds; it continues from where it left off.

How to Respond

Perform the surgery mini-game to remove it, always following this exact order: Scissors, Transplant, Scissors, Transplant, then 3 random Treatments. Shooting, tasing, or offering coffee to the Tendril will automatically kill the patient, so avoid those approaches.

Quick tips

• Follow the exact surgery mini-game order to remove it: Scissors, Transplant, Scissors, Transplant, then three random Treatments.
• Never shoot, tase, or offer coffee to the Tendril — all three of those actions automatically kill the patient instead of helping.
• Remember the timer doesn't reset if you restart the surgery, so don't waste time — get the item order right the first time.
