Does anyone know the Mermaides heart events? I've already had the first one in Daryl's basement. If anyone knows the times of her other heart events I would really appreciate it. Also, what does it take to get married? Do I have to find a certain number of Harvest Sprites? Also, how do I upgrade my bed? I've upgraded my house, bought the table and the clock, but I haven't been able to find anything else for sale in the Harvest Sprite TV shopping.
