That is so funny! I experimented with one investigating with Patrick Burns. Not sure if it worked, but we all stood around it just like the spirits in your cartoon! It attracts more than just ghosts, apparently.
There are currently no widgets assigned to the left-sidebar, place some!
Once you add widgets to this sidebar, this default information will go away.
Widgets can be added by going to your dashboard (wp-admin) -> Appearance -> Widgets, drag a widget you want to see into one of the appropriate sidebars.
