Start-ater

A very useful imitater varient, unlike most plants you buy it from a shop, each time you buy it you get 1 use out of it, and you can only use it once per round (and only once per try on survival endless), it costs 0 sun, and it gives you a row of sunflowers, and a row of peashooters to start you off (each one costs 25k) Also, there is the pro version for 55k a piece, that gives a double row of sunflowers, a row of repeaters and a row of wallnuts.

Note
If it is on a pool type level it will come with lillypads (and if it requires certain types of lillypad/pot and extras to keep the plants working, it comes with that too), and if its night it will be sunshrooms rather than sunflowers.
