Look at this picturePlease elaborate.
Now turn your head and look at it upside down. His eyes are birds/robins.....the one bleeding on the left is a Robin....who is dead.
*Joker's eyes are different than everyone else, so are his teeth*
The mouth is Batman. The eye is Robin. Basically showing how connected he is to the death of Robin and always talks about Batman.
