Are Lego's Getting Angrier As They Age?

Are Lego's getting angrier with age?

A new study out of New Zealand is showing the darker side of the popular toy.

Their little figures appear to be getting meaner, at least by appearance.

Researchers examined 6,000 of the popular toys figures.

They found the number of smiley face Lego's is decreasing.

They're being replaced with angry faces and more weapons.

Researchers say all those frowns could have a negative impact on how children play.

Kids around the world spend 5 billion hours playing with Lego's each year.
