The Hollow event in Roblox features a special Piggy quest that rewards players with the Hollow 2026 Badge and the Substance Survival Belt UGC item. However, completing this challenge requires you to finish several objectives, including collecting candles, activating a hidden portal, solving obstacle courses, and defeating the final boss.
The quest also includes a timed boss encounter where you must collect Planks, build bridges, and solve puzzles while avoiding enemy attacks. If you’re having trouble completing the challenge, this guide explains every step you need to follow to earn the Substance Survival Belt.
How to Start The Hollow Quest in Piggy
To unlock the special Hollow challenge, you first need to enter a specific Piggy map and collect three candles. These candles are required to activate the portal that takes you to the event area.
Step 1: Select Forest Chapter 4
First, launch Piggy on Roblox and open the map voting screen. Select Forest Chapter 4 as your preferred map, then choose Bot mode when selecting the game mode.
Bot mode is recommended because it makes the challenge easier to manage while you search for the required items.
Once the match begins, explore the map and collect three candles. They are scattered across different areas, so you may need to check several locations before finding all of them.
Pay special attention to areas around machines and benches, as candles commonly appear near these objects. While searching, remember to avoid Piggy so you don’t get caught before completing your objective.
Step 2: Activate the Hollow Portal
After collecting all three candles, your next objective is to find the portal somewhere on the Forest Chapter 4 map.
Approach the portal and use the candles to light it. Once all the required candles have been placed, the portal will activate and open the entrance to The Hollow.
Walk through the activated portal to enter the special quest area and continue with the next challenges.
How to Complete The Hollow Obby in Piggy
After entering The Hollow, you must complete two different obstacle courses before reaching the boss fight arena. Both sections require careful movement, as falling from the platforms can interrupt your progress.
Step 1: Complete the First Obby
The first obstacle course requires you to jump across several platforms to reach the middle platform. However, not every platform is safe to stand on, as some of them will disappear when you move across them.
Take your time and pay attention to the platforms ahead. Avoid making unnecessary jumps, especially when you are unsure whether a platform is stable.
I also recommend adjusting your camera angle so you can see the gaps and landing positions more clearly. This makes it easier to plan your next jump and avoid falling.
Step 2: Follow the Correct Symbols
After reaching the middle platform, you will encounter another obstacle course. This time, the challenge involves memorizing a sequence of symbols to identify which platforms are safe.
Pay attention to the symbols displayed during the puzzle. You must remember their order and step on the matching platforms as you move forward.
For example, one recorded sequence consisted of:
- Moon
- Star
- Dot
Your combination may be different, so don’t blindly follow the example above. Memorize the sequence shown in your own game and use it to cross the platforms.
Once you successfully complete the second obby, you will reach the boss fight arena.
How to Survive The Hollow Boss Fight in Piggy
The final challenge is a boss encounter with a ten-minute time limit. Your objective is to complete three different puzzle stages by collecting Planks, building bridges, and activating a Cannon.
You also need to avoid the Hollow Entities and the boss’s attacks while exploring the arena. Since time is limited, try to complete each objective efficiently instead of spending too long in one area.
Step 1: Collect Planks Around the Arena
At the beginning of the boss fight, search the surrounding area for Planks. These items are scattered throughout the arena and are required to construct bridges.
Collect as many Planks as necessary before moving toward the building areas. Keep exploring while watching out for the enemies that patrol the arena.
Step 2: Reveal the Puzzle Solution
After collecting the Planks, look for the tentacles around the arena. Interact with them to reveal the solution needed for the next puzzle.
Pay attention to the symbols or sequence displayed, as you will need this information when activating the Cannon.
Make sure you remember the correct order before moving to the next objective.
Step 3: Build Bridges to Reach Higher Areas
Use your collected Planks to construct bridges around the arena. These bridges allow you to access higher platforms and reach areas that would otherwise be inaccessible.
Follow the available paths and continue building bridges until you reach the next puzzle location.
Be careful while moving between platforms because the Hollow Entities and boss can attack you during this process.
Step 4: Activate the Cannon
Once you reach the higher area, locate the Cannon and interact with it. You must enter the correct puzzle symbols in the order revealed by the tentacles.
The combination changes between runs, so there isn’t one universal code that works for everyone. Always check the puzzle solution in your current attempt before entering anything.
After entering the correct sequence, the Cannon will activate and allow you to progress to the next stage.
Step 5: Repeat the Bridge and Puzzle Challenges
Activating the Cannon doesn’t immediately finish the boss fight. You must complete three separate stages, each involving bridge construction and puzzle-solving.
Repeat the same general process for every stage:
- Search the arena and collect Planks.
- Interact with the tentacles to reveal the puzzle solution.
- Use the Planks to build bridges.
- Reach the higher area and locate the Cannon.
- Enter the correct symbols in the required order.
- Avoid the Hollow Entities and boss attacks.
Complete all three stages before the ten-minute timer reaches zero. Once you successfully finish the encounter, you will complete The Hollow quest in Piggy and receive the event badge.
How to Claim the Substance Survival Belt UGC in The Hollow
After completing the boss fight, you will receive the Hollow 2026 Badge in Piggy. However, you still need to return to the main Hollow Event Hub to collect the actual UGC reward.
Follow these steps to claim the Substance Survival Belt:
- Return to The Hollow Event Hub.
- Find the portal associated with Piggy.
- Approach the pedestal located near the Piggy portal.
- Interact with the pedestal to claim the Substance Survival Belt.
- Collect your reward and check your Roblox inventory.
After completing the process, you will receive the Substance Survival Belt UGC item, an additional event badge, and 10 Hollow Tickets.
The Hollow quest in Piggy requires players to complete several challenges, starting with collecting three candles in Forest Chapter 4 and activating the hidden portal. After entering The Hollow, you must finish two obstacle courses before facing the final boss.
The boss fight is the most challenging part because you only have ten minutes to complete three bridge-building and puzzle stages. Once you finish the encounter, return to The Hollow Event Hub and interact with the pedestal near the Piggy portal to claim the Substance Survival Belt UGC and your 10 Hollow Tickets.
