When a capsule lands without eliminating any objects, the handy bottle will fill up. An empty bottle requires five capsules to land before it is filled, though some bottles start out partially filled. When a Handy Bottle is filled, the labelled objects will be shot out at random locations. In some stages, the locations in which the objects are shot may be prioritized. The object(s) a Handy Bottle shoots out is based on what is labelled on it, which can include an exploder, a shell, a skill charger or a pop cannon. In some cases the objects are contained, such as being hidden in Brick Blocks. The amount of objects that a bottle shoots out depends on the size. A small-sized Handy Bottle that occupies one row and one column shoots out either one or two objects, a medium-sized Handy Bottle that occupies two rows and two columns shoots out either two or three objects, while a large-sized Handy Bottle that occupies three rows and three columns shoots out either three or four objects. With the exception of clouds, if a bottle is covered in an object such as ice or barrels, it will not be able to fill until the foreign object is removed. Moreover, when Dr. Rosalina's skill in rearranging capsules is active, landing a capsule won't fill the bottle.
