Halloween Part 3
Join us for the third part to the halloween event!
Capybaras VS Plants is a Roblox idle game where you hatch capybaras, set them to fight plants, and collect coins even while you are offline. This guide covers the core loop, the weather and mutation system, the Dr. Carrot Event's new content, and how to earn and spend Scrap.
The loop starts with an egg and ends with a bigger collection. Plants generate coins whether you are logged in or not, so every session begins by collecting what built up while you were gone. Spending those coins on new eggs keeps the cycle moving.
The next survey is being prepared.
Weather occurs randomly during a session and triggers mutations on your capybaras and plants. A mutation changes the affected unit's stats. The Mega Scroll, available in the Scrap Shop for 1,000 Scrap, lets you deliberately apply a Mega Mutation that multiplies stats by 2.1.
Events running now or coming soon. They have fixed dates, so check them first.

The event introduced a robot-themed update with new collectibles and a separate currency called Scrap, which is tracked independently from coins. Plants in the event fall into two groups: the Robot line and the Dr. Carbot Boss line.
| New capybara | Robot Capybara MkII (Secret rarity, hatched from a dedicated egg or bought for 750 Scrap) |
| Robot line plants | Carbot, Mecha Melon, Circuit Pepper, Holo Petal |
| Boss line plants | Dr. Carrot, Dr. Carbot MkI, Dr. Carbot MkII, Dr. Carbot MkIII |
| New currency | Scrap (separate from coins, spent in the Scrap Shop) |
| New scroll | Mega Scroll (grants a 2.1× Mega Mutation, costs 1,000 Scrap) |
Scrap accumulates automatically whenever you collect robot-type items. Different items award different amounts per collection. Once you have enough Scrap, the Scrap Shop lets you trade it for packs, the top capybara, or Mega Scrolls.
| Robot Capybara MkII | 300 Scrap per collection |
| Holo Petal | 200 Scrap per collection |
| Robot Mushroom and Dr. Carbot MkIII | 100 Scrap each per collection |
| Circuit Pepper and Robot Capybara | 50 Scrap each per collection |
| Robot Seed Pack | costs 40 Scrap in the Scrap Shop |
| Robot Capybara MkII | costs 750 Scrap in the Scrap Shop |
| Mega Scroll | costs 1,000 Scrap in the Scrap Shop |
Holo Petal was introduced on August 15, 2026, as part of the Dr. Carrot Event. Its base income of 20,000 coins per second places it among the strongest Secret-rarity plants in the game. It was available exclusively through the Robot Seed Pack during the event, with the Premium version offering double the odds. Mutations and other modifiers can push its displayed income above the base 20,000/s figure.
The game distributes gift codes that reward in-game bonuses. As of September 9, 2026, there are four working codes tracked for this game. The codes themselves are inserted live on this page rather than printed here.
Yes, plants generate coins offline as well as online.
You can hatch it from its dedicated egg or buy it directly from the Scrap Shop for 750 Scrap.
Mutations trigger randomly when weather occurs in a session, and they can affect both capybaras and plants. If you want to guarantee a Mega Mutation, use a Mega Scroll from the Scrap Shop.
