“Catch and Feed a Brainrot” is a Roblox idle RPG developed by ping bong, launched on June 2, 2025. Players capture creatures called Brainrots using a lasso tool, feed them fruits to evolve them into higher rarities, and earn in-game currency (Cash) passively. The game’s offline progression system allows Brainrots to generate income and farms to produce fruits even when players are offline. With over 36 million visits, it has become a popular title, challenging players to collect rare Brainrots and dominate server leaderboards as the wealthiest player.
Mechanism
The gameplay loop is engaging and multifaceted, combining capturing, nurturing, and upgrading mechanics:
- Catching Brainrots:
- Players equip the lasso tool by pressing the ‘1’ key.
- Approach a Brainrot in the wild and hold ‘E’ to start a clicker-style battle, clicking repeatedly to fill a progress bar and capture the Brainrot.
- Higher rarity Brainrots require upgraded lassos, with upgrades available at the board next to the Sell station using Cash.
- Placing on Plots:
- Captured Brainrots are placed on one of up to six unlockable plots, which generate Cash passively.
- Additional plots can be unlocked with Cash, expanding the player’s capacity to hold Brainrots.
- Equipment like the Golden Sprinkler can be added to plots to enhance performance.
- Feeding and Evolving:
- Feeding Brainrots with fruits grants experience points (XP), enabling them to level up and evolve into higher rarities.
- Special fruits, such as the Chillimelon, can trigger significant evolution jumps (e.g., from Uncommon to Mythic).
- Upgrading:
- The lasso can be upgraded to capture rarer Brainrots (e.g., Level 10 for Epic, Level 14 for Legendary).
- Farms can be upgraded up to level 275 to improve fruit quality and production rates.
- Plots can be enhanced with equipment to boost Brainrot efficiency.
- Offline Progression:
- Brainrots and farms continue generating Cash and fruits offline, ensuring continuous progression.
- Premium Features:
- The premium shop offers boosters, Cash bundles, game passes, and relics, purchasable with Robux.
- Gifting items (fruits or relics) is possible by holding the item, approaching another player, and pressing ‘E’.
Lasso
The lasso is the primary tool for capturing Brainrots. Initially, it can catch Common and Uncommon Brainrots, but upgrading it with Cash at the board next to the Sell station allows players to target higher rarities. For example, a Level 10 lasso is required for Epic Brainrots, and a Level 14 lasso for Legendary ones. Upgrading the lasso is crucial for progressing in the game, as rarer Brainrots generate significantly more Cash.
| Lasso Level | Brainrot Rarity Accessible |
|---|---|
| 1 | Common, Uncommon |
| 10 | Epic |
| 14 | Legendary |
Plots
Plots are designated areas where captured Brainrots are placed to generate passive Cash. Players start with one plot and can unlock up to six using Cash. Each plot can hold one Brainrot, and adding equipment like the Golden Sprinkler enhances the plot’s efficiency, boosting both Brainrot performance and nearby farm productivity. Managing plots effectively is key to maximizing income.
| Plot Feature | Description |
|---|---|
| Unlockable Slots | Up to six plots can be unlocked with Cash. |
| Passive Income | Brainrots on plots generate Cash per second. |
| Equipment | Golden Sprinkler boosts plot and farm efficiency. |
Characters (Brainrots)
Brainrots, the core collectible units, come in six rarities, each tied to different levels of passive income:
| Rarity | Description |
|---|---|
| Common | Lowest rarity, minimal Cash generation. |
| Uncommon | Slightly higher income than Common. |
| Rare | Moderate income, more valuable. |
| Epic | High income, requires Level 10 lasso. |
| Legendary | Very high income, requires Level 14 lasso. |
| Mythic | Highest rarity, maximizes earnings. |
A Secret tier is reportedly in development but not yet available. Higher rarity Brainrots generate more Cash per second, making them essential for topping leaderboards. Specific Brainrot names or designs are not widely documented, but their visual and functional differences add variety to the collection process.
Fruits
Fruits are the primary resource used to level up and evolve Brainrots. Feeding a fruit to a Brainrot provides it with XP. Different fruits offer varying amounts of XP, and some rare, mutated fruits can provide a significant boost, potentially allowing a lower-tier Brainrot to evolve into a much higher one almost instantly. For example, a Chillimelon can evolve an Uncommon Brainrot directly into a Mythical one.
| Source | Description |
|---|---|
| Food Pump | Initial fruit source, upgradable for better quality and faster production. |
| Plant Farm | Grows random fruits every few seconds, harvestable for feeding. |
| Greenhouse | Advanced structure for enhanced fruit production. |
| Golden Sprinkler | Equipment that boosts farm productivity when added. |
Potions
Potions are consumable items that can be used to apply mutations to Brainrots. These mutations provide boosts to cash and XP gain and are distinct from the standard variants like gold, diamond, void, and shiny. Potions are available for purchase, and the stock of available potions rotates periodically.
Some of the known potions include:
- Rainbow Potion
- Wet Potion
- Lightning Potion
- Glitch Potion
Relics
Relics are special items that grant passive buffs to a player’s earnings and production. They can be purchased from the “Buy Relics Here” stall, which is located at the back of the player’s plot near the Relics Garden. The shop’s inventory of relics resets every five minutes, and players can also pay Robux to reset it instantly. To access the relic shop, players must first upgrade their plot to level two.
Relics come in different rarities, with higher rarities offering more significant bonuses. These bonuses can include increased cash from feeding Brainrots (“Feed cash”), a multiplier for the cash generated by characters (“character cash”), and an increased rate of fruit mutation.
Here is a list of known Relics and their effects:
| Relic Name | Rarity | Effects | Cost |
| Champion Statue | Common | Increases Feed cash. | 25B or 49 Robux |
| Peace Pond | Uncommon | Increases character cash and Feed Cash. | 450B or 149 Robux |
| Sakura Blossom | Rare | Increases Fruit mutation rate and Feed Cash. | 67.2T or 300 Robux |
| Honey Haven | Epic | Increases character cash, Feed cash, and Fruit mutation. | 5.7QD or 599 Robux |
| Legend Statue | Legendary | Increases Plant EXP, character cash, and Feed cash. | 246.7QD or 799 Robux |
| Eternal Ember | Mythical | Increases Plant EXP, character cash, Feed cash, and Fruit mutation. | 96.4QT or 1,299 Robux |
| Mythic Statue | Premium | Grants a 10x growth and money multiplier. | 799 Robux |
| Frosty Statue | Premium | Grants a 3x growth and money multiplier. | 199 Robux |
Farms
Farms produce fruits for feeding Brainrots and can be upgraded up to level 275 to maximize output. Key farm types include:
| Farm Type | Description |
|---|---|
| Plant Farm | Basic farm, grows random fruits every few seconds, harvestable for feeding. |
| Greenhouse | Advanced farm, produces higher-quality fruits for better XP gains. |
| Golden Sprinkler | Equipment that enhances farm productivity, increasing fruit output. |
Farms operate offline, ensuring a steady fruit supply. Upgrading farms to higher levels improves fruit quality and production speed, while equipment like the Golden Sprinkler further boosts efficiency. The maximum level of 275 allows for optimal fruit production, supporting rapid Brainrot evolution.
Codes
As of July 2025, “Catch and Feed a Brainrot” does not have an in-game system for redeeming codes. The developers have not announced any plans to implement a code system in the future. Therefore, there are currently no active or expired codes for the game. Players looking for updates on this can follow the developers’ official social media channels, such as the Ping Bong Discord server and the X (formerly Twitter) account of developer @developercelex.
