Handy box

A handy box is a stage feature in the shape of a question block from Dr. Mario World. These items only appear in stage mode. When a capsule matches is made next to them or that they are eliminated through skill or item, the handy box will randomly reveal a beneficial stage object, which could be one of the following items: Dr. Toadette and Dr. Lakitu's stage mode skills change viruses or objects that can be eliminated (except capsules or coins) into handy boxes. The Random! stage item may also change a virus into a handy box. If the object converted into a handy box is a colored object (e.g. viruses, colorful crates), the object within the handy box will also have the same color. Handy boxes that are converted from an object will not contain skill chargers.
