Once the six Cattle have appeared (below the two CG30s), eight UFOs will slowly fly into view, from the left and right sides of the screen; once you have fired a shot at each of them to kill them, three more UFOs will slowly fly down into view from the top of the screen. Once you have fired a shot at each of them to kill them, a twelfth UFO will fly into view from the left side of the screen, then beam up the second Cattle as the text of "HELP" appears upon the screen - and once you have fired a shot at this UFO to kill it, the text "THANK YOU" will appear on the screen as the Cattle slowly falls back down to the ground (but, if you accidentally shoot the Cattle itself, the text of "OUCH" will appear on the screen, as it moos from the Yamaha YM-2610). Three more UFOs will then slowly fly down into view, from the top of the screen; once you have fired a shot at each of these to kill them, a sixteenth UFO will fly into view from the right side of the screen, and beam up the fifth Cattle as the text "HELP" appears on the screen. Once you have fired a shot at this UFO to kill it, the text "THANK YOU" will appear on the screen as the Cattle slowly falls back down to the ground (but again, if you accidentally shoot the Cattle itself the text "OUCH" will appear on the screen as it moos from the Yamaha YM-2610) - and four more UFOs will then fly down (and up) into view from all four corners of the screen. Once you have fired out a shot at each of them to kill them, six more UFOs will slowly fly into view from the left side of the screen; once you have fired a shot at each of them to kill them two more UFOs will fly into view from the right side of the screen and beam up the fourth and sixth Cattle as the text of "HELP" appears on the screen. Once you have fired a shot at both of these UFOs to kill them, the text "THANK YOU" will appear on the screen as both of the Cattle slowly fall back down to the ground (but once again, if you accidentally shoot either of the Cattle themselves, the text "OUCH" will appear on the screen, as they moo from the Yamaha YM-2610) - and six more UFOs will then fly down (and up) into view from the top-right and bottom-left corners of the screen. Once you have fired a shot at each of them to kill them six more UFOs will fly into view from the left side of the screen; once you have fired a shot at each of them to kill them, two more UFOs will fly into view from the left side of the screen, and beam up the first and third Cattle, as the text "HELP" appears on the screen. Once you've fired a shot at both of these UFOs to kill them, the text "THANK YOU" will appear on the screen as both of the Cattle slowly falls back down to the ground (but yet again, if you accidentally shoot either of the Cattle themselves, the text "OUCH" will appear on the screen, as they moo from the Yamaha YM-2610) - and you'll then receive 5000 points for every Cattle you still have (and if you still have all six, you will receive a "PERFECT" bonus of 20000 points), along with the points for every UFO you killed (there were forty-two).
The game will then return to the zone selection screen (and you will have ten seconds to choose between World 4A and World 4B); however, if you are playing the US version, you'll proceed to World 4A (or "Round 33"). The song heard from the Yamaha YM-2610 in both worlds is also another new one.
