Ay Mi Gatito — Update 36

Ay Mi Gatito — Update 36 Complete Guide

If you've spent any time on the internet in the last couple of years, the Mi gatito Miau Miau song needs no introduction. It spread across TikTok, YouTube Shorts, and gaming streams in waves, becoming one of those cultural earworms that people still share well past its original viral peak. When Steal a Brainrot made it official with Update 36 and dropped Mi Gatito as a secret brainrot, players already knew exactly what they were looking at. There was no learning curve, just instant recognition.

That is the specific alchemy this game pulls off repeatedly: take something already living in people's heads, give it a number and a cost, and let the familiarity do the work. The "Ay Mi Gatito" update is one of the cleanest examples of that approach in the game's history, and it produced three brainrots worth understanding in detail.

What Update 36 Added

The title character was not the only addition. Update 36 introduced three brainrots, all landing in the secret rarity tier and all currently unobtainable through standard gameplay:

Mi Gatito is the direct reference — the brainrot form of the viral song character. At $3.25M/s income and a $725M buy cost, it sits toward the lower end of the secret tier for raw numbers, but secret rarity always carries trade weight that the income stat alone does not reflect. Players who recognize the reference will pay for that recognition.

Los Mi Gatitos is the upgrade form of the same concept — a full pack of them, more income ($6.5M/s), higher cost ($1.2B). The dual nature is reflected in the name shifting from singular to plural. If you are building a complete Mi Gatito set for your display, this is the natural companion piece.

Popcuru and Fizzuru operate in a completely different tier. At $170M/s income and a $135B cost, these two are among the highest income-generating brainrots in the entire roster. The dual-name format mirrors other powerful pair-style brainrots that tend to be endgame targets.

How to Obtain These Brainrots Now

All three were available during the Update 36 window and are now locked. Players have two realistic routes today:

Trading is the primary path for Mi Gatito and Los Mi Gatitos. Because both brainrots are tied to a culturally recognized song, they attract strong demand from collectors even when raw income stats do not justify the price on paper alone. Before any deal, check the values page for current community estimates — trade values shift week to week and a single check can save you from a bad deal.

Fusion still works for Popcuru and Fizzuru. This is one of the less obvious facts about this update: even though Popcuru and Fizzuru are listed as unobtainable, the fusion recipe remains active. Using the required OG brainrots as ingredients gives a 16% probability of crafting the duo. This recipe works in both the new and old eras. That makes Popcuru and Fizzuru one of the only unobtainable secret brainrots you can still build without trading.

Fusion Strategy for Popcuru and Fizzuru

A 16% success rate means you should expect to attempt the recipe roughly six to seven times before a successful output on average — though RNG can run short or long. Practical advice before you start:

• Stock up on OG ingredients first. Running out of input brainrots mid-session wastes time and can be expensive to recover. Decide how many attempts you can afford and gather all ingredients before opening the fusion machine.
• Track your attempts. Some players underestimate how many runs a 16% chance requires and give up right before a successful fuse would have landed. Keeping a count helps you stay patient.
• Compare fusion cost to trading cost. If you already hold tradeable secrets, it may be faster to swap for Popcuru and Fizzuru directly. Use the fusion calculator to map out whether the OG ingredient cost is justified versus what the brainrot trades for.

Mutations and Traits

Getting the brainrot is the first step. What actually multiplies its effective value are mutations and traits.

Standard mutations are available to any brainrot through normal gameplay:
- Diamond — 1.5x multiplier, 5% spawn rate (the highest-accessibility standard option)
- Gold — 1.25x multiplier, 10% spawn rate

Limited mutations can only be applied during special in-game events and offer dramatically higher multipliers:
- Phantom — 12x (the highest multiplier currently in the game)
- Divine — 10x
- Cursed — 9x
- Radioactive — 8.5x
- Galaxy — 7x

On a $170M/s brainrot like Popcuru and Fizzuru, a Phantom mutation pushes effective income well beyond $2 billion per second. These are the combinations that endgame players build toward, and they justify the grind for high-income secrets like this one.

OG traits layer on top of mutations. They trigger during special in-game events and are applied randomly to brainrots on the Red Carpet. The best currently available are Strawberry (9x), Meowl (8x), John Pork (7.5x), and Skibidi (7x). When one of these events activates, any secret brainrots you have placed are eligible — including all three Update 36 additions.

Tips and Strategy

For collectors: Mi Gatito is the cultural centerpiece of this update and the one people will recognize on sight. Los Mi Gatitos is the natural complement. Both are display-worthy for anyone building a themed collection around internet culture references.

For income-focused players: Popcuru and Fizzuru is the real target. At $170M/s base income it dwarfs both other Update 36 brainrots, and the active fusion path means you do not have to rely on finding a trade. Once you obtain it, prioritize a limited mutation — a Phantom on this brainrot is one of the most impactful upgrades in the game.

For traders: All three carry unobtainable status, which keeps supply tight. Los Mi Gatitos in particular sometimes trades at a relative discount because fewer players track the "pack" form of a brainrot. This can be a smart acquisition if you plan to hold.
