Obby: Steal Monster Egg!

Welcome to the awesome game “Obby: Steal Monster Egg!”, which will keep you hooked for hours. Today, you’ll be hunting for rare eggs, running from Brainrot patrols, and building a collection of unusual monsters. It doesn’t seem all that complicated. All you have to do is find an egg and bring it back to base. But the more valuable the loot, the more dangerous the path to it becomes. The guards won’t let you take your find without a fight, so you’ll have to calculate your speed and plan safe escape routes. Once you’ve successfully returned to your base, you can place the egg in an empty slot and wait for a new monster to appear. Each pet is uniquely rare and valuable, and also generates income.

To reach the most valuable specimens, you’ll need to constantly improve your abilities. To do this, you’ll have a treadmill where you can increase your character’s speed. This will make it easier to outrun fast guards and return with loot from distant areas. You can invest the coins you earn into upgrading your training and expanding your pen, thereby increasing your base’s capabilities.

How to Play?

Head into the guarded zone and find the egg you want to collect. Approach it and hold down the interaction button to pick up your loot. After that, your main goal is to escape the area and avoid falling into the clutches of the angry Brainrot. Once you reach your base, return to the pen and place the egg in an empty spot. Wait for it to hatch and for a new monster to emerge. After that, your pet will automatically start bringing you coins, which you can use to buy upgrades and new abilities.

Use the treadmill to level up your character. Train, earn running points, and increase your speed level to move faster across the map and outrun pursuers. Don’t forget to upgrade the treadmill itself—more effective training will help you prepare for new expeditions faster. You can also spend the coins you earn on upgrading your base, where your pets are housed. Once the nearby areas no longer pose a serious challenge, try venturing into more distant areas to collect eggs. Rarer monsters may await you there, but the risk of encountering guards will be higher. Keep an eye out for nest updates at the start of each new game day, regularly expand your collection, and use your pets’ earnings to make upgrades.
