Steal an Egg keeps growing with new events, and the Monsters Are Coming update brought one of the most requested items in the game. The Flyswatter has become a must-have tool for anyone serious about defending their eggs. This guide breaks down exactly how to get it, what it does, and why the grind is worth the effort.
What Is the Flyswatter in Steal an Egg

The Flyswatter is a combat item added during the monster update. It works like the other bats and weapons already in the game, but with its own flair. Players use it to hit rivals who are chasing the same egg. A solid hit can knock someone off balance and slow their run back to safety. That small delay is often the difference between keeping your loot and losing it at the last second.
We think of the Flyswatter as a defensive tool first. It gives you a way to protect eggs you have already claimed. If someone tries to snatch your prize before you reach the safe zone, a well-timed swing buys you the extra seconds you need.
The Hungry Monster Event Explained
Everything about the Flyswatter runs through the Hungry Monster, sometimes called the Hungry Frog. You will find this creature sitting near the entrance to the safe area, close to the Fuse Machine. It only wants one thing: parasites pulled from infested eggs.

Infested eggs look like the regular nest eggs scattered across the map, except they carry a glowing purple parasite on top. These eggs start appearing from the Snow biome onward, so players need to push past the early zones to find them. The parasites vary in size, and it helps to know that size does not always signal value. A small parasite still counts the same as a large one toward your feeding total.

Once you spot an infested egg, pick it up and carry it back to the Hungry Monster. Hold the interact button and choose the Feed Parasite option. Each feed fills the monster’s belly meter by twenty percent. You need five feeds to reach 100%.
How to Collect Monster Chests
Filling the belly meter is only step one. Once the monster reaches full, it hands over a single Monster Chest. This chest is currently the only route to a Flyswatter, so understanding how the odds work matters.
The reward pool inside the chest is weighted, not random guesswork. Here is how it breaks down based on the current event data:

- 1.25x Egg Growth boost, roughly 43.5 percent chance
- 1.25x Speed boost, roughly 30 percent chance
- 2x Treadmill Speed boost, roughly 20 percent chance
- Flyswatter, roughly 5 percent chance
- Monstrous Egg, roughly 1.5 percent chance
That table tells us something useful. Most chest openings hand out temporary buffs rather than permanent items. The Flyswatter sits well below the growth and speed boosts, which explains why so many players open several chests before seeing one drop. The Monstrous Egg is even rarer, so anyone chasing that reward should expect a long grind on top of an already long grind.
Why the Grind Takes So Long
The math behind this event is simple once you lay it out. Five parasites equal one chest. One chest gives roughly a one-in-twenty chance at the Flyswatter. That means most players will need to repeat the parasite hunt multiple times, sometimes feeding the monster four or five separate rounds before the item finally appears.
We recommend treating each chest as a bonus rather than a guaranteed reward. Focus on covering ground efficiently instead of chasing a single lucky roll. Farming infested eggs in the Snow biome and beyond, then making quick trips back to the Fuse Machine area, keeps your feeding loop tight. The less time you waste walking, the more chest attempts you fit into a single session.
It also helps to check the View Rewards prompt on the Hungry Monster itself before you start. This shows the full odds table in-game, so you always know what you are working toward.
Tips to Speed Up Your Flyswatter Grind
A few small habits make this event less painful. Consider these before your next run:
- Scout the Snow biome and later zones first, since infested eggs will not spawn in earlier areas.
- Grab infested eggs even if the parasite looks small, since size does not change how much it fills the meter.
- Stay close to the safe-zone route so you can carry the eggs back quickly without getting caught.
- Track how many chests you have opened, since the drop rate evens out over a larger sample size.
None of these tips guarantee a fast drop, but they cut down on wasted time. Since the Flyswatter only comes from a weighted chest pool, efficiency is the only real lever players can pull.
Final Thoughts
The Flyswatter rewards patience more than skill. There is no shortcut around the five percent drop rate, and no way to buy it directly. What players can control is how quickly they cycle through the feeding loop. Keep hunting infested eggs, keep feeding the Hungry Monster, and keep opening chests. Eventually the odds catch up, and that Flyswatter lands in your inventory, ready to defend your eggs the next time a rival gets too close.
