Rexosaurus Hatcherini in Plants Vs Brainrots is a new Secret rarity Brainrot that arrived as part of the Story Update of the game. This update was released on October 18, 2025, and introduced five new Secret rarity Brainrots in total, along with a brand-new biome. You will find Rexosaurus Hatcherini within this biome.

It’s a Brainrot that resembles a Tyrannosaurus Rex that hasn’t fully hatched from its egg yet. Its tail, head, arms, and legs have all emerged from the shell, while its body is still cocooned inside it. Here’s the complete guide on how you can get it and how much it earns for you.

Getting Rexosaurus Hatcherini in Plants Vs Brainrots

There are two distinct ways to acquire this Brainrot in the game. They are:

Get one from the Treadmill inside the Desert Biome.
Get it as a gift from another player.

From the Desert Biome

The first method is the more practical approach to obtaining this Secret Brainrot, although it involves quite a bit of grinding. You’ll first need to unlock access to the Desert Biome if you want to get Rexosaurus Hatcherini this way. To unlock the biome, you must complete all 25 story missions. There aren’t any shortcuts you can take here.

Each mission becomes progressively more challenging and will test your defensive abilities. Picking the right plant to defend against the waves is key. This requires you to spend some time learning how each wave progresses and which plants in your garden can counter them.

Even if you fail the first few times, don’t worry. You can retry each mission in less than an hour after failing. You’ll also receive some rewards even when you fail. So, there’s no downside to failing and learning. Once all 25 missions are completed, simply wait for Rexosaurus Hatcherini to appear on the Treadmill.

Gifted by Another Player

A less likely way to obtain the Brainrot is if another player gifts it to you. However, for that to happen, you might have to offer another Secret rarity Brainrot in exchange. Even so, most players wouldn’t be willing to part with such a rare Brainrot from their collection. So, it’s best to try the first method.

How Much Does Rexosaurus Hatcherini Earn?

Once you acquire the Secret Brainrot, it will begin earning around $4.3k per second for you. While that isn’t close to the highest earnings from a Secret rarity Brainrot, it’s still a significant amount that adds up quickly. Rexosaurus Hatcherini can contribute substantially to your overall cash flow.
