On an island, there is this strange pattern - boys always lie while girls always tell the truth. Now you encounter five children.

The oldest one says, "The number of boys among us is an odd number."

The second one says, "The number of boys among us is an even number."

The middle one says, "The number of boys among us is a prime number."

The fourth one says, "The number of boys among us is a composite number."

The youngest one says, "The number of boys among us is a perfect square."

Convert the five children to a number based on their order of birth. Then submit your answer as the sum of the numbers of the boys **only**. For example, if you think only the youngest child is a boy, then your answer is 5. If you think only the middle three children are boys, then your answer is 2+3+4=9.
