What does Mega mean for Grow a Garden 2 pets?

Mega is the largest pet size. Mega pets are rarer than Big, and Mega Rainbow is the rarest size+type combination.

How is the “1 in N” rarity calculated?

We divide an assumed ~50 million unique gardeners by how many of that exact variant exist in census snapshots, then round to two significant figures. Only pets rarer than about 1 in 100,000 are listed.

Why do some pets show “??????” or very high 1-in-N?

Extremely rare combos may have zero or near-zero known copies in the census. Those still rank at the top; counts refresh as new snapshots arrive.

Why are Garden Valley and Fall Harvest listed separately?

Each world keeps its own inventory, so a pet belongs to exactly one world's save and the two censuses are counted independently — the same combo can be far rarer in one world than the other. Fall Harvest pets do turn up in Garden Valley (Magic Mail ships Fall→Main), and once there they are counted on the Garden Valley board. The Fall Harvest board only lists Fall-spawn pets — Garden Valley species have no path into a Fall save.

Rarest Pets

The rarest pets that exist right now — including Rainbow, Big and Mega — ranked out of ~50M gardeners.

This is a live rarity index for Grow a Garden 2 pets. Each pet's rarity combines three things — its species tier, its size (Big or Mega) and whether it's a Rainbow variant — into a single "1 in N" figure based on real ownership data across the player base.

“1 in N” = out of ~50M gardeners, roughly how many you'd sift through to find one. Figures are rounded and refresh as live data comes in.

Each world is counted on its own — pets live in that world's inventory, so Garden Valley and Fall Harvest numbers aren't comparable. Fall pets can show up in Garden Valley too: Magic Mail and world travel carry them across.

How pet rarity is calculated

We start from real census data — periodic snapshots of how many of each pet variant actually exist across players — and divide the game's player base (we assume roughly 50 million unique gardeners) by that count. So if a variant exists on about 50 accounts, that works out to roughly "1 in a million." Every figure is rounded to two significant digits so the numbers stay clean and clearly approximate.

Size and Rainbow stack on top of a species' base tier, which is why the headline combinations are so scarce: a Mega Rainbow of a top-tier species is the rarest thing a pet can be. The list only includes pets rarer than about 1 in 100,000 — anything more common than that isn't really a "rarest pet."
