I have made a couple of skins into the game, mainly the Marigold. It currently has the most skins in the game totalling up to 3 different skins. WOW!
I have used the default Marigold skin to look like the PvZ2 sprite, but more dedicated to its ability look than its base look.

Then there is the MariGOLD skin:

And the “Plants vs Zombies” skin:

The MariGOLD skin will be unlocked by purchasing it, and the “PvZ” skin will be unlocked by using NO Sunflowers, and instead use Marigolds as a replacement (No sun producing things, and have Marigold).

Btw a new type of plant (not a new plant, nor family) will be coming… take your guesses in the comments. Winner gets a shout-out.
