In Grow a Garden, pets have abilities that can apply mutations, duplicate crops, increase variant chance, and more.
Players start with 3 pet equip slots, but can get up to 8 pet equip slots by trading in aged pets.
You can obtain pets by buying Pet Eggs from the Pet Shop or Event Shops and hatching them.
To hatch an egg, you must place it on an empty spot in your garden and wait for the hatching period.

Grow a Garden Seedling Pet Wiki

The Seedling in Grow a Garden is a Mythical pet that was added in the Beanstalk Update.
You can get it from the Sprout Egg from Goliath’s shop at a 12% chance.
To unlock the shop, you and other players must fully grow the beanstalk (you must contribute at least twice).
The Seedling swaps mutations between two different random fruits every 5 minutes (ignores favorited fruits).
