Explanatory note: These creatures are not the same in the game HKO as of 2011 anymore. This entry describes a Beta-creature of 2008. Fierce Spooky Trees have been renamed to Fierce Treedrops and will now drop very different things. Only one Fierce Treedrop can be found in Wind pathway as of 2011, many more of them are running around all over the area South Wind Grassland.
All content that might not be be suitable or just too sad for children has been removed from HKO before release in 2009; including death of pets, creatures, NPCs and your own character. You cannot kill creatures virtually ingame in HKO anymore but can only put them to sleep for a while. So they also won't drop body-parts after being defeated but stuff like "fury", "growl", "treasure", "feather" or "powder" and such instead.
