In Survive Overnight in a Mega Store, players can get all 20 Hollow Event Tickets by collecting 18 Candies and stirring them in the Cauldron. But this is challenging, as new players may struggle to find them. If you are confused about how to proceed, here is a detailed guide.
How to Start the Hollow Event Guide in Survive Overnight in a Mega Store
To start the Hollow Event in Survive Overnight in a Mega Store, enter the experience from the game page. Once inside, join the lobby through any portal on the main screen.

The quest objective in Survive Overnight in a Mega Store is simple: collect 6 candies of each of the three variants in the store and place them in the Cauldron. So, in total, you must collect 18 candies as soon as possible. You can find the Cauldron right at the store entrance, with the Candy Count on top.
How to get Candies Survive Overnight in a Mega Store
As mentioned earlier, the objective is to collect six candies for each variant. With 3 variants, you need to collect 18 candies total. The main way to get candies is through the Pumpkin Chest present throughout the map. You can only open these chests at night. So, try to spot as many as you can during the day and open them at night. To make your life easier, I have listed a few locations where you can usually find Pumpkin Chests.
Pumpkin Location 1

You can always find a Pumpkin Chest inside the Weapons Purchase area. Walk straight from the Cauldron, then turn left to find the Weapons area.
Pumpkin Location 2

The next Pumpkin Chest is right at the center of the Map. This Chest is on the left or right wall in the center corridor running from the north to the south side of the Map.
Pumpkin Location 3

Another common Pumpkin Spawn location is the Graveyard, or cemetery, at the back of the Map. Here, you can always expect a Pumpkin Chest right at the center.
While you are at the cemetery, I urge you to open all the Coffins, as they usually contain Candies or even secret rooms with one or more Pumpkin Chests.

Interact with the Coffins to remove their tops, then place them nearby to access their contents. This lets you collect Candies even during the day instead of waiting for the cycle to turn night.
The other way to collect Candies is to kill the employees. This is risky, as they can quickly form groups, and there is no guarantee they will drop Candies after you eliminate them. So, it's better to avoid this particular method while farming Candies.
How to stay alive in Survive Overnight in a Mega Store

While collecting Candies, you also need to stay alive. Focus on getting a weapon like the Katana to help you eliminate employees who try to attack you at night. Also, eat and drink any food you spot to boost your energy and stamina so you can evade the chasing monsters. You also can't restore your Health immediately; it regenerates slowly over time if you don't take any damage.
After collecting all 18 Candies, stir them in the Cauldron to get the 20 Halloween Tickets & the Hollow - A Tasty Brew Badge.
