These guys are fun. The "Talking Heads" stop a whole line of marbles, get one in their mouth drop it to the track below and then come back up for the next marble in line. The head dips and returns for each marble until they have all been passed to the steel track below. The marble leaves the first head then runs around toward you and back into the second head. This one repeats the process, but since the marbles are already spaced apart by the head before it, it just tips, not having to keep any marbles back while it drops it to the track below.
The first two heads get three marbles at a time. The first set of three marbles is captured by a marble collector after the second talking head. The second set of three balls adds to the first three and tips the arm. These 6 then go through the second two talking heads, and are finally released into three long sections of wavy track. All 6 racing back and forth across the wavy track.
