Grow a Pet Fighter is a Roblox simulation tycoon by God Bless Zak 7 built around a short, repeating loop. You hatch eggs into pets, feed those pets to raise their level, fuse them into stronger versions, then send them into the Arena or the Tower. Pets also earn cash while you are logged out, which is why the game rewards short sessions spread across the day.
Quick answer: Buy a food bowl for $60 to hatch A Strange Egg into a Level 1 Frog, feed it bones collected around the arena, then fuse it with a second pet to jump several levels at once.
The six systems that drive progression
Everything in the game hangs off six connected systems. Nothing else happens until you own a pet, so the egg is always the first move.
| System | What it does |
|---|---|
| Eggs | Source of every pet you own |
| Pets | Your fighters and your income |
| Arena | Battle mode, plus bones and coins |
| Tower | Climb mode, floor by floor |
| Fusion | Combines two pets into a stronger one |
| Cash | Buys bowls, eggs, and fusions |
The Arena and the Tower are parallel options, not a sequence. Both accept pets, and neither is locked behind the other.
Hatch your first pet from A Strange Egg
You know the hatch worked when the pet appears in its enclosure at your base with a name and a level tag above it, such as Frog Lv.1.
Feed bones to raise pet levels
Bone treats are scattered around the perimeter of the arena, and they are free. Head out from the base, run the outer ring, grab everything on the ground, then return and drop them into the bowl. Each feed pushes the pet up a level.
The Food Bowl itself can be upgraded, and the upgrade is what carries a pet past the point where plain feeding stalls. An upgraded bowl took Jumpy Boi from Level 4 to Level 5, and later bone runs around the Mammoth in the arena pushed Sir Hops to Level 6.
Collect bones on the same trip you collect coins. Both sit in the arena, so one lap covers levelling and income at once.
Fusion: the fastest way to a stronger pet
Fusion takes two pets and returns one. It is the only progression the game documents outside feeding, and it is where the real power jumps come from. Open the PETS screen, pick your main pet, then select a partner from the grid to combine with it.
A worked chain from a fresh account looks like this, with each result carrying forward into the next fusion.
| Pets fused | Result | Level / stat |
|---|---|---|
| Frog + Breadcrumb (Pigeon) | Jumpy Boi | Frog Level 3 |
| Jumpy Boi + Hop Along (Bunny) | Sir Hops | Frog Level 5, cost $94 |
| Sir Hops + Lizard | Ribbit Rex | — |
| Ribbit Rex + Hamster | Puddle | 213 HP |
Breadcrumb came out of a Nest Egg, and the Bunny, Lizard, and Hamster each came from later eggs. Fusion costs cash, so keep a small buffer before you commit. The $94 charge on the Sir Hops fusion was more than the price of the first food bowl.
Fusion consumes both pets. Check the result preview before confirming, because the partner you feed in is gone afterwards.
Send pets to the Arena and the Tower
The TO ARENA button at the bottom of the HOME screen moves you out of the base and into the fighting area. That is also where you take the pet for a walk into the central zone.
The Tower runs floor by floor, and there is no published top floor. Progress tracks your pet’s level rather than anything you do during the run, so treat each attempt as a measurement. A Level 4 Jumpy Boi cleared to Floor 4 before being knocked out, while an earlier attempt with the same pet stopped at Floor 3. Note the floor you die on, feed or fuse, then run it again and compare.
Where to collect coins and cash
Coins drop in the centre of the arena, clustered around the Golden Ostrich and the Mammoth. Run between the two, sweep what has dropped, and carry it back to bank it. A single focused loop of the centre took one balance up to $594, which is enough for several bowl upgrades and a fusion.
Your pets also generate cash while you are offline, so logging out with pets in place is part of the loop rather than a break from it. The game sells a single pass, 2x Money for 199 Robux, which doubles what you earn.
Claim the free Thunder Egg from the group
There is one free egg on offer for joining the developer’s Roblox group. Open the rewards panel in game, hit JOIN GROUP, and the Thunder Egg unlocks as the group reward.
If the button does not respond, join the God Bless Zak 7 group in a browser tab and return to the game. The reward has landed when the Thunder Egg appears as claimable on that same panel instead of showing the join prompt.
A repeatable session plan
- Bank whatever your pets earned while you were offline.
- Run one arena lap for bones on the perimeter and coins in the centre.
- Feed everything you picked up, then upgrade the Food Bowl if you can afford it.
- Hatch one egg so you have a fusion partner ready.
- Fuse, then test the new pet in the Tower and note the floor.
Servers cap at eight players, so the arena is rarely crowded and bone routes stay reliable. If you want to check the current build yourself, the experience sits on its Roblox page, where the update date and live player count are listed alongside the four-line description the developer wrote.
