Thus far I have received a magus, bovis, up to 246 coins, 8 stamps, 9 potions, numerous different habitats . . . and some other frogs I don't recall. I'm convinced the winnings are randomized like the gift boxes in the pond are.
I think it's faster to gain happiness in the pond, but you never know what the reward may be when the puzzle is completed.
How hard do you find the puzzle?[]
In the beginning I found the puzzle VEEEEEEEERY difficult. The first time I actually finished it, It had taken 1/2 an hour of my life. But then it got easier and easier, even though it is different each time XD. How hard do you find it?
