Bubble Bobble/Levels 11-20

Level 12
The safest place to stand is the nose of the face, and simply blow bubbles at the monsters as they go past. Bubbles float up from the bottom of the screen, to the left and right of the nose, then down the columns, where the monsters first start off, as per the picture. The trapped monsters will float down to their starting locations. Water bubbles will float up from the bottom of the screen and move to the starting point of the monsters also. To avoid becoming trapped in the columns, wait until a water bubble appears on either side before leaping into the side bar to pop any bubbled monsters floating therein. The water will pull you through the small gap. If you get trapped, you can 'climb' out but this takes a lot of practice to time right.

Level 13
Bubbles arrive from the bottom, and float to the top of the screen. The enemy remains in the central heart; the easiest way to get them is ride a bubble into the heart and defeat the enemies therem. Alternative attacks involve popping water bubbles before they pass through the top of the heart to trap monsters on the water stream that suddenly appears.

Note: If extend bubbles leave through the top, they're gone forever. Pop them as soon as possible for their bonus.

Level 14
Move to the lower-left platform, face left and kill the ghost as he comes down. Go over to the right platform and trap the second ghost, then stand there and trap as many of the purple things as will fly down to the bottom. Then go fall down the left hole, and when you come through the top land on the structure and move to the right. From there, trap the rest of the flying purple things. Then jump down and pop them all.

You may want to avoid entering the lower holes when the map starts - the

Level 15
Jump quickly to the second level and remove the three monsters there. This is easer if played with two players since the players can move the bobbled enemies to each other and pop the bobbles when meeting. Then a bobble jump is needed to get to the next level. Preferable on the left side since there should be no monsters. The monsters on the top floor can be put into bubbles without any danger by jumping close to the wall in a way that the jumping dragon does not touch the monsters but the bubbles will appear and catch the monsters.

Level 17
When you enter this screen, you will see two large Bubble Busters flying past with captives.

Level 19
Be careful not to fall into the small paths - if you slip into one of them, there is no way out.

Lightning bubbles will appear and float up half-way from the left or right, before going through the vertical barriers to the center. Jump into them and face away from the direction you want to shoot them.

Level 20
Wait on the water bubbles to appear and let yourself be taken to the upper part of this level. If you haven't lost any life, you'll get the symbol for the Secret zone (in the upper left part of the screen).
