From Nookipedia, the Animal Crossing wiki
The Balloon Series is a furniture series that first appeared in Animal Crossing: New Leaf. The furniture pieces are structured out of balloons. Balloon items can be obtained only by shooting down the presents floating on balloons in the sky and sometimes as gifts from villagers. Pietro's house contains most of the Balloon Series.
*In PAL regions, the item is the "Balloon-Poodle Lamp".
