Piggy Hidden Ending Code & TIO Guide

Lab code translator

Before you start

This is the Book 2 Hidden Ending that awards the skin shown as “???” in the community wiki, commonly called TIO. Book 1’s Plant True Ending is a different quest.

The official Roblox Hidden Ending badge was enabled when checked on October 26, 2026, with recent awards recorded. The route below is a sourced walkthrough, not a playthrough we completed ourselves.

• The current community guide requires at least one player with all the other normal Book 1 and Book 2 completion and ending badges, including Plant, Factory and the other Lab endings. Event badges and the Maple Donut Secret Badge are excluded.
• Have the qualifying player enable Savior Ending in Settings. The community guide also tells teammates to enable it; have everyone do so before starting.
• Stay in the same server throughout the quest. A private server and a friend make map voting and distracting the bot easier, but the community guide lists solo completion as possible.
• If a friend supplies the required badges, that friend must complete the Docks step with Pony following them. Simply having them in the lobby is not enough.

Docks: escape with Pony unharmed

1. Choose Book 2, Chapter 9: Docks. Any mode is reported to work; Player mode with a cooperative friend controlling Piggy makes Pony easier to protect.
2. Complete the normal escape while keeping Pony away from the Infected. If he is attacked and sits down, restart Docks.
3. The player with the required badges must escape with Pony following them. In a larger group, let the other players escape first, then have that player leave with Pony.

Field note. The community troubleshooting notes also warn against activating Umbra during this step. Keep this run focused on the normal Docks escape.

Camp: enter 467854 on Swarm

1. Choose Chapter 11: Camp on Swarm mode.
2. Find the Blue Key and open the blue door at the top of the watchtower. Use the keypad inside.
3. Enter 467854 and press the green check mark. Wait for “PASSCODE ACCEPTED”. Once accepted, you can die or escape to end the round; completing the map is unnecessary.

Field note. If the keypad is missing, check the Docks escape, the qualifying player’s badges and the Savior setting. The community guide suggests replaying Factory’s Savior ending if toggling the setting and repeating Docks still fails.

Lab: read the four vents in order

Choose Chapter 12: Lab on Bot mode. Open the map until you have the Wrench, then remove all four vent covers. Read the numbers in this order:

1. The vent near the player spawn.
2. The vent beside the room with the yellow safe.
3. The vent outside the blue keycard door.
4. The vent inside the blue keycard room.

• Enter those four numbers into the translator above. Each number becomes its English word: for example, 4 becomes FOUR. Enter the corresponding symbols for all four words, without spaces or separators.
• Match each drawing against the game’s keypad. Both the vent numbers and the arrangement of the keypad buttons change each round.
• Have a teammate distract the bot while you enter the sequence. Press the green check mark after the entire sequence. “PASSCODE ACCEPTED” starts the cutscene and the next phase.

Field note. A wrong submission locks the keypad for that round. Restart Lab and read the new numbers; an old screenshot or a friend’s code is not a reusable password.

Clear the five chase puzzles

After the cutscene, TIO chases you through five familiar puzzle rooms. Use each room’s clues rather than memorizing another player’s answers.

1. Alleys: find the three displayed numbers and their positions, then enter the three-digit keypad code.
2. Ship: read the colours clockwise from the left wall: near left, far left, far right, near right.
3. Docks: align the pillar’s three layers with the numbered clues. The pillar uses Roman numerals: I = 1, II = 2, III = 3 and IV = 4.
4. Temple: each wall sign identifies a side of the wheel and the symbols that belong there. Rotate the rings until all sides match.
5. Camp: find the red-dot clues and press the corresponding lights on the circular puzzle. Once the way opens, avoid the traps and enter the black passage.

The final fight: six item handoffs

Keep moving through the maze while looking for the first three weapons. Give them to the matching characters:

1. Wooden Sword → Pony.
2. Baseball Bat → Georgie.
3. Pipe → Zee.
4. After all three are helped, the upstairs area opens. Find the Bone and take it to Doggy upstairs.
5. Take the Carrot to Bunny upstairs.
6. Take the Grass to Zizzy upstairs. Once all three upstairs characters have attacked TIO, the ending cutscene plays.

Field note. The first three handoffs can be completed in any order; so can the three upstairs handoffs. Watch for the dark and white Sentinels upstairs. The sourced reward is the Hidden Ending badge and the ??? / TIO skin.

If a step fails, where do you restart?

• Pony is attacked in Docks: repeat Docks with Pony protected.
• Camp says “SYSTEM LOCKED”: end that round and retry Camp on Swarm. Death after an accepted Camp code is allowed.
• The Lab keypad locks, or you die in Lab or the Hidden Ending phase: restart at Lab on Bot mode, still in the same server. Re-read all four vent numbers.
• You leave or switch servers: start the quest chain again. Do not rely on a reconnect preserving your progress.
• A helper has the badges but Camp’s keypad never appears: confirm that the helper actually escaped Docks with Pony, and check the Savior setting before repeating the run.

Field note. These retry rules come from the community guide. Its server-persistence notes do not establish that progress survives every disconnect or change of teammates.
