In PvZ, once you unlock the Zen Garden, there is a chance you can get a plant, or chocolate (used to feed plants or Stinky the snail). What I want to know is; What is that chance?
And now that there are different copies on different consoles, is there a difference between them? I.e. Console vs. PC vs. Android/Apple?
Best Answer
Chocolate
It can be obtained in all game modes, with the exception of the Zen Garden itself.
Once ten pieces of chocolate have been amassed, no more chocolate will appear.
How to obtain it
Little "cheat"
I'm not able to find a source which defines a specific drop-chance.
Presents
Presents drop very rarely and they may give the player Zen Garden plants, Chocolate or unlockable games.
Presents that appear after level 5-4 contain Zen Garden plants.
Where to get a present
Which level is the best to get plants
Trivia
For your second question here is a link to a list with all differences in all available versions (could not find anything about differences in obtaining chocolate).
That are all information I found to your questions. If I find anything new I'll update.
