Bubbu 2 - My Pet Kingdom

Review by eFreeware

The pitch behind Bubbu 2 is one of the stranger ones I have come across in the pet-care genre: your cat is the first kitty on Mars. Bubadu builds a whole world around that idea, with day and night, rain and sunshine, and rainbows you can bring into being, all while you keep a virtual cat fed, rested and in good spirits. The space setting is what separates it from the many cat games that never leave the living room.

It is a free casual game rated for Everyone, and the audience is not hard to guess. This is built for children and for families who want something gentle to share, and for anyone who likes the ritual of checking in on a pet each day. If you are after a demanding simulation or a competitive challenge, the tone here is clearly aimed elsewhere.

Adopting a cat and keeping him well

Everything starts with adoption. Once Bubbu is yours, the daily loop is care: he needs to be happy, healthy, fed and well rested, and you are the one keeping those plates spinning. It is a familiar structure for anyone who has played a virtual pet before, and the Mars backdrop gives the routine a bit of novelty.

There is also a medical side. Bubbu sometimes does not feel well, and at the animal hospital you help treat his tummy and throat, fix his bones and teeth, and deal with fleas. These are small caretaking puzzles rather than anything clinical, and they give the routine a second reason to come back beyond feeding and sleep.

What appeals to me about this arrangement is that it stays hands-on. You are not just watching numbers move; you are brushing teeth, patching up a cat and putting him to bed. For a younger player, that is a lot of small, understandable tasks to work through in a session.

The hatchery, the merging machine and a growing kingdom

The collecting layer is where Bubbu 2 tries to be more than a care game. A hatchery lets you make alien friends for Bubbu, and a merging machine takes two pets and combines them, with a new egg hatching as the result. That loop of combining and hatching gives the game a progression hook that a plain pet sim does not have.

There is also a fashion salon, stocked with outfits and accessories for dressing your cat. It is a cosmetic layer rather than a mechanical one, but for the audience this game is courting, dressing up Bubbu is likely to be as much of a draw as any of the mini-games.

The world itself is meant to be explored rather than just maintained. Bubbu's travels take in the whole kingdom, plus the city and the lake, and there are new friends to meet, among them Cocco the hen and Mimmi's hologram. Those characters are small additions, but they give the map a bit of personality beyond the cat himself.

Mini-games that fill out the sessions

A rotating set of mini-games sits alongside the care routine: Pixel Color, Egg Stack, Mars Explorer, Marble World, Pop It, Alien Invaders, Pizza Maker and others. Memory, creativity and coordination are the skills these are meant to exercise, which is a reasonable description of what short, colorful activities of this sort tend to do.

Playing them feeds back into the main game. The mini-games help you level up the pet adventure, earn achievements and collect rewards, so they are not a separate mode you dip into and forget. That integration is what keeps a game like this from feeling like a bundle of unrelated toys.

The variety is the point. A stacking game, a coloring activity and a simple arcade shooter ask for different things from a player, and for a child working through a session, that switching is part of the appeal. It also means there is usually something to do that does not require the same attention as the care loop.

Ads, purchases and the subscription

Bubbu 2 is free to play, and that comes with the usual strings. Ads in the game promote Bubadu's own products as well as outside ones, and tapping them can take players elsewhere.

A subscription is offered as well, and it keeps renewing until you switch it off, with a day's notice needed before the period runs out. It can be managed and canceled through your Google Play account settings, which is the standard arrangement on the platform. If a subscription is part of your plans, that cancelation window is the detail worth remembering.

For privacy, PRIVO, an FTC-approved safe harbor, certifies the game as COPPA compliant. That certification is the kind of thing a parent should expect to see on a game rated for Everyone, and it is stated plainly here.

What kind of player this fits

The clearest fit is a younger child who likes animals and responds to the idea of looking after something. The tasks are everyday ones, the world is bright, and the mini-games are short enough to fit into the gaps in a day. Parents looking for a game they can hand over without a long explanation will find the structure here familiar.

Older players who enjoy pet sims for the management side may also get something out of it, particularly the hatching and merging loop, which adds a collection goal on top of the care routine. The Mars theme gives it a bit more character than the average cat game.

The numbers suggest a large audience: more than 10 million installs and a 3.9 average across 46,315 ratings, with 196 written reviews. That is a lot of people trying it and a decent, if not glowing, reception. It first appeared in December 2023, and the most recent update, in August 2026, was described simply as technical improvements.

A gentle pet sim with a space twist

Bubbu 2 does a few things well: it gives a virtual cat a genuinely unusual home, it wraps the care routine in a collection system with the hatchery and merging machine, and it offers a spread of mini-games varied enough to hold a child's attention. The medical tasks and the fashion salon round out a package that is clearly built for its audience.

The trade-offs are the ones you would expect. It is free with ads and in-app purchases, a subscription renews automatically unless canceled in time, and the whole experience is pitched at a young player rather than someone wanting a deep simulation. None of that is hidden, but it is part of the deal.

If you are looking for a calm, colorful pet game to share with a child, or you simply like the idea of a cat exploring Mars, this one is built for exactly that. It is not trying to be anything more ambitious, and on its own terms it looks like a reasonable way to spend a few minutes each day.
