As a longtime Grow a Garden player, when the Fall Market / Fall Festival rolled in, I was excited to see what new pets and strategies would reshape the mid-to-late game. In this article I'll walk you through all the Fall pets relevant to your list (Red Squirrel, Chipmunk, Sugar Glider, Space Squirrel, Marmot, Robin, Badger, Grizzly Bear, Barn Owl, Swan, Salmon, Woodpecker, Mallard, Red Panda), analyze their passive abilities, compare which ones you should prioritize, and give practical tips on how to use them in your garden. This is not an ad — it's just a fellow gardener's take.

Before diving into pets, a quick recap of how the Fall event works:
With that, let's go through each pet on your list, match them to what's publicly known, and what role they play.
Below is a breakdown of the pets you asked about, what is known of them in the Fall event (or baseline pet system), and how they can fit into your garden strategy.
| Pet | How to Obtain / Notes | Passive / Ability | Best Use / Role | Caveats / Tips |
|---|---|---|---|---|
| Robin | One of the Fall Egg pets (common tier) | It decreases player size by 10% per pet (shrinking effect) | Use to reduce your size footprint — helps with movement / garden navigation when many pets / effects active | Because it's common, you can stack several; but shrinking too much might feel awkward |
| Badger | Also a Fall Egg pet | Applies the “cracked mutation” (4× money) every 5 minutes | Good for periodic money boosts / mutation triggers if you're in mid-late game | The 5-minute interval is fixed, so more badgers = more frequent triggers |
| Grizzly Bear | Another Fall Egg option | Increases player size by 8% and applies fall mutation | Combines well with Robin: you can fine-tune your size (shrink vs grow) and also benefit from fall mutation | If your size becomes too large, movement or pet collision might be annoying |
| Barn Owl | In the Fall Egg pool | Adds 0.1–0.25 kg base weight to shop pets, and grants +0.80 XP/sec | Excellent for long-term scaling: helps your other pets grow in weight, gives passive XP | Because it's rare in the egg pool (1.5% drop rate) you may need patience or many eggs |
| Swan | Also in Fall Egg (divine tier) | Mimics other pets' abilities and applies the “graceful mutation” | Very versatile — acts like a jack-of-all-trades pet if you have many pets to mimic | Because it mimics, its strength depends on your current pet lineup |
| Chipmunk | A shop pet (Fall Pets Shop) unlocked through contributions | 6–12% chance to not consume a Harvest Tool when using it | Useful in tool-heavy workflows — saves your tool durability or consumption cost | The percentage is modest, so stacking more gives diminishing returns |
| Red Squirrel | Shop pet unlocked via contributions | Reduces cooldowns of fall-type pets by 14.60 seconds when their ability finishes | Very strong if you have multiple Fall-specific pets (because it speeds up their reuse) | If you don't have many fall-type pets, its effect is less noticeable |
| Marmot | Shop pet unlocked through more contributions | Occasionally burrows underground; when found, it gives a random fall-related reward; later burrows again with a 15–30% chance | Acts like a “mini treasure dropper” — nice extra yield occasionally | It's somewhat random, so don't rely on it for consistent income |
| Sugar Glider | Shop pet (requires higher contributions) | Every ~19.55 minutes, it glides over 3 random fruits and copies 1 mutation from each to the next fruit | Excellent for mutation farming / spreading good fruit mutations | Timing matters — coordinate gliding windows with your harvest cycles |
| Space Squirrel | Shop pet (premium / late unlock) | Every ~17.53 minutes, it has ~15.41% chance to apply Voidtouched mutation (135×) on random plants | This is one of the “endgame money pets” — a great source of huge multipliers if luck is on your side | Because it's rare and expensive, only get it once you have solid base setup |
| Salmon | Shop pet (later unlock) | Grants bonus experience for each additional Salmon in your garden | Useful for XP stacking if you have many Salmon | The bonus is more linear — stacking many copies gives more benefit |
| Woodpecker | Shop pet (or possibly through event) unlocked via contributions | Occasionally consumes a woody fruit and brings it to the crafting table, reducing crafting time | Good utility if you often craft wood-based items or seeds | Its effect is intermittent — don't expect constant reduction |
| Mallard | Shop pet (later in the shop path) | Every hour, Mallards fly out of the garden and leave a random reward, then return | Passive “bonus drop” pet — solid when you don't have many active tasks | The hourly interval means you'll miss some if you leave the game for long stretches |
| Red Panda | Shop pet (unlocked by highest contribution threshold) | Occasionally visits the Gear or Seeds shop and restocks a random item | Very useful for helping maintain shop stock or restock rare seeds / gear | The “occasionally” means it's bonus, not a guarantee — it's more of a quality-of-life pet |
If you're aiming to round out your lineup, focus on synergy first—pair cooldown pets like the Red Squirrel with mutation spreaders such as the Sugar Glider, and layer in utility options like the Marmot or Woodpecker for consistent returns. Endgame collectors will eventually want high-impact choices like the Space Squirrel or Red Panda, but balance is key along the way. For players who prefer a quicker route, you can always buy Grow A Garden pets directly from trusted marketplaces to save time.
From my experience and seeing how the community talks, here's how I'd prioritize and strategize building your Fall pet roster:
Also, always consider synergy. For example:
