Optional Bosses

Fight or spare Trapezist, Chameleon, and AI — every skip, combat tip, and Stay warning in one place.

Last updated:

Endacopia’s three optional bosses each grant a fight achievement and an avoid achievement. The pairs are mutually exclusive on a single save, so 100% needs at least two boss-routing runs. A dedicated Stay (Ending C) attempt should fight all three — skipping any boss on that file can block the secret ending.

Keep Steam on patch 1.08+ (Patch Notes). Softlocks around Trapezist tent entry, Chameleon combat, and core-room pauses were fixed across 1.01–1.03.

Trapezist — Fatal Performance / Cut The Act

Reach the platform

  1. Clear the crowd in front of the main trapeze tent (microphone booth: tell the crowd to leave)
  2. Complete the circus act QTEs: trapeze line → blue ball → hoop → trampoline (Space at peak) → unicycle → cannon
  3. Land beside the Trapezist

Fight — Fatal Performance

  • Talk to her and start the battle
  • She kicks balls into left / middle / right lanes
  • Punch balls as they pass in front of you (not only block)
  • Standard stamina rules: M2 block, M1 counter (Controls)

Avoid — Cut The Act

As soon as you land beside her, equip the Scalpel (from Circus Whack-a-Mole → Medical Tent chain) and cut the rope / wire on the left. Do not start the fight dialogue.

Stay warning: Fight Trapezist on your Stay run — Cut The Act belongs on a separate 100% avoid run.


Chameleon — No Strings Attached / Case Closed

Before the den

Read the Chameleon’s name on a Timesville graveyard headstone. It is usually Ozzie, sometimes Ollie — re-check every playthrough.

Avoid — Case Closed (five answers)

StepPromptAnswer
1Who are youAsk who he is
2NameType the grave name (Ozzie / Ollie)
3His filmIt was impactful
4What aboutHis story (not the victims)
5ThemeIrony

All five correct → he leaves → Case Closed.

Fight — No Strings Attached

Refuse the peaceful answers / choose combat:

  • Block when a puppet arm bends
  • Punch the side (arm or head) that leans forward
  • Patch 1.03 fixed fight softlocks; 1.04–1.05 cleaned chase music and VHS edge cases

Stay warning: Fight Chameleon on Stay runs.


AI — System Override / Short Circuit

Encountered in the Office Core after the colored-button open sequence (slowest → fastest: Green → Yellow → Black → Red on the relevant Chapter III / late Office revisit).

Prepare the avoid item

  1. Fill a transparent mug / cup with water from the Office cooler
  2. Keep the filled cup in inventory before opening the Core

Avoid — Short Circuit

Answer the Core questions: Green O → Green O → Red X, then immediately pour the water on the outlet in the front-left corner. Some players report a crash after the pour — relaunch; progress and the achievement should stick.

Fight — System Override

Any other dialogue path, then fight in the middle of the room:

  • Punch round flesh circles before they become eyes
  • Punch rib cages as they appear
  • Stamina may be higher or lower depending on prior boss fights

Stay warning: Fight AI on Stay runs. Short Circuit is the rarest avoid (~10% at launch).


  1. Run A (story + fights): Toy Saw → Escape, fight all three bosses, side content (Achievements)
  2. Run B (avoids + Return): Real Saw → Return, Cut The Act + Case Closed + Short Circuit
  3. Run C (Stay): Chapter I reload → fight all bosses + three Stay SecretsChapter III return to Mellow’s room

Frequently Asked Questions

Q: Can I get fight and avoid for the same boss in one run? A: No. Each pair needs a second playthrough (or a pre-boss reload).

Q: Do optional bosses appear in the demo? A: No — full game only.

Q: Which boss should I avoid first? A: On a dedicated avoid run, do Trapezist (Scalpel rope) first while the Scalpel is still in inventory logic, then Chameleon quiz, then AI water skip.

Where do I get the Scalpel for Cut The Act?
