User blog:Puzzlemaster34/Help me with this survival endless build idea

I have a strategy I would like to share, but i don't know where to put everything yet.

I know it'll look something like this:

(G) (g) (W) (F) F _ _ _ _

(W) (O) (W) (W) (g) g F _ _

|T| |c| |C==C| (|U|) (|W|) (|g|) (|g|) (|g|)

|T| |c| |C==C| (|U|) (|W|) (|g|) (|g|) (|g|)

(W) (O) (W) (W) (g) g F _ _

(G) (g) (W) (F) F _ _ _ _

Legend:

I don't know if I want Spikerocks yet...
 * Pumpkin
 * | Means plant/plants is on lily pads/a lily pad
 * C==C Cob cannon
 * F Fume shroom
 * G Gatling pea
 * _ Empty space
 * g Gloom shroom
 * c Cattail
 * O Umbrella leaf
 * U Gold magnet
 * T Twin sunflower
 * W winter melon

If you have any ideas on how to improve this build, without changing it too much, please do share them!
