Flourishing seeds (2015)

Flourishing seeds are the components of the Pet of Spring, and are won through playing Treasure Hunter, or awarded while doing Herblore. 500 of them were required to make the pet. They are only tradeable in equal quantities for charred branches, lush blossoms, or fallen leaves. These items are completely removed from the game two weeks after the promotion ends.

The number of seeds obtained appears to be based roughly on the amount of experience gained, rather than the number of actions the player does. 20 seeds were also rewarded for handing in a Daily challenge.
