31 - Throbbing Crystal of Joy[edit]
32 - Twisted Shaft[edit]
This is a difficuly level, because the twist within the cylinder makes aiming slightly more difficult. The slight twist to the right means that an enemy that appears to be directly in front is actually to your left.
In this stage, enemies always arrive in fixed waves as a mixture of grunts, flowers and aggressive boffins. You will have to eliminate all enemies to trigger the next wave.
33 - Time for Tea[edit]
This level introduces a new enemy: The Feedback monster. As shown in the level image, it appears as a small cloud. It approaches like other grunts, and may be pushed off the grid provided you have the power zone extended. However, they will cause a visual distortion if they are shot directly. When they reach the end of the grid, they will hold their position for a few seconds before departing. Unlike the grunts, contacting them without a power zone is instantly fatal, without a small window to use the superzapper.
You will recognize their approach by a purple beam.
34 - Dissonance[edit]
This is a simple level, still meant to introduce you to the new enemy.
35 - The Blue Room[edit]
A standard level. Nothing special compared to other nearby levels.
36 - Daisy Is A Cow's Name[edit]
A standard level. Nothing special compared to other nearby levels.
37 - Pasto verde, boi gordo[edit]
A standard level. Nothing special compared to other nearby levels.
38 - Down in the tubehole[edit]
The camera position is close in this level, and the flowers have a tendancy to grow quickly. In addition, the top part of the grid is a blind zone if you are waiting near the top of the grid.
39 - Uphill gardening[edit]
The camera position is close. While the edges of the level are normally safe, it may be difficult to see what is happening in the middle of the grid.
On this level, the flowers tend to grow for a small distance, but launch quickly.
40 - ...with the power of an ox![edit]
The lower ears of the ox are difficult to see, allowing enemies to remain somewhat hidden. Staying near the middle should be safe.
