Here are some great pictures found of some very odd things that do not look natural, yet are. This is a transparent frog the round balls you can see i n the belly are eggs. I guess this frog is called a glass frog.
A beehive that looks like a vase
A tree that looks like a person, I do not know if they trimmed it that way or if it grew like that, maybe it kinda looked like a head to begin with and they trimmed it after, anyway, I think its awesome even if it is kinda creepy.
