Boomseed

Boomseed
Boomseeds are items from the Meet Cosmo adventure. They are small, light green, spiky seeds that, once the player collects them, appear in the upper-left corner of their screen. When dragged from the box, they will blow up after a few seconds, killing Phantoms and Phantom Sprouters in the area.

Recipe
To make Boomseeds, the player must combine Honey, Nectar and Chomper Seeds in Cosmo's bowl. Then, they can harvest the seeds from Boomseed Trees.
