The Boomseed Tree is a non-member den item. It can be obtained from the bottom left chest after completing the adventure Meet Cosmo on Hard Mode.
The Boomseed Tree is a large tree just like the boomseed trees found in the phantom adventures. It has a thick, striped, knobby trunk and five large boomseeds. When clicked while in a den, the boomseeds will disappear. When the boomseeds run out and the player clicks the tree, they will regrow.
- When clicked on in a den, the boomseeds will vanish one at a time and all return once none remain.
