You see a fallen tree.
Location
All around Tiquanda, including Chor (here) and between two buildings in Banuta (here), Arena and Zoo Quarter, Queen Eloise's basement (accessible during mission 7 of What a Foolish Quest, here), Underground Glooth Factory (here).
Notes
According to a sign in front of the fallen tree in the Arena and Zoo Quarter, the eyes belong to a ratmonkey, which might be a reference to the Sumatran rat-monkey created by Peter Jackson for his 1992 film Braindead and later referenced in the 2005 remake of King Kong.
