Gravity Boy Action Toy is an item you get from the fourth catalog, 1st Person Shopper and is the last item in the catalog.
A crudely looking child-like toy makes that monkey noises when touched. Other objects are drawn towards it.
Unlike the Mini Moon, Miniature Sun, etc, Gravity Boy Action Toy does not float but instead is affected by gravity. It is effected, however, by other gravitational pulls like the Mini Moon's, Tiny Galaxies', etc.
When burned, it screeches like a monkey and combusts. Afterwards, roses appear, which can be burned. It cost 120 coins and takes 3 minutes to deliver.
His attraction is undeniable.
