A stick that has special effects
The stick held by Grookey was originally a branch from the forest where troops of Grookey live, but it’s no longer a simple branch. It has gained special powers after being exposed to the energy within Grookey’s body.
It can give energy to plants
Its green fur creates energy from sunlight. Wilted flowers and leaves have been seen to regain their color when Grookey drums with its stick near them.
