Players who have interacted with other Tiny Farm members via Com2uS/Gamevil’s HIVE community or the unofficial message board at Proboards would have most likely come across the claims that breeding in front of the original Love House — the one with a pair of lovey-dovey cows on the sign — will up the chances of successfully obtaining higher tier or event animals.
The origin of this belief comes from the fact that either the Talking Cow or Talking Dairy Cow said something about breeding in front of it will make dreams come true or something. I don’t know the exact words and no one remembers them but they all claim that it was something to that effect. (The dialogue has been removed or changed for some time now.)
I do recall that, for a while (and maybe it’s still going on), the animals DID give legitimate gaming hints such as where to go to find the option to redecorate the map. But those kinds of tips were perceivable and the Love House claim being something that can’t be seen is what makes it dubious.
