In the Android phone and tablet version of the game, Stinky can continue collecting coins while the player is doing something other than viewing the Zen Garden. If Stinky is fed chocolate and the game is either exited or minimized, however, the game will forget that Stinky has been fed chocolate. It will also forget that chocolate has been fed if the player does not check on Stinky within the hour time limit of the chocolate's effect. This whole mess means he or she can feed Stinky chocolate, go play survival mode for 59 minutes, and return to discover it has collected you 10,000 coins, or something of the sort. Just do not close the game accidentally.
