The stat block here is designed with an encounter in mind in which the Dread Gazebo moves all about the map, smashing everything in its path and hailing rocks and debris down on the party. Creating an environmental hazard they have to avoid while trying to identify what brought the Animated Object to life and destroy or dispel that.
The Elemental itself is far more interested in smashing about and creating havoc than interacting with the party. Which is good- since it hits pretty hard especially for parties around level 7-.
