The 2016 Zoo Boo was last weekend and it was a blast per usual.

The Ellen Trout Zoo hosts the Zoo Boo every year, and they never fail to pack the zoo full of costumed hopefuls dressed in their Halloween best.

Here are some of the cutest ... and scariest costumed critters we saw on the first night of the Zoo Boo. Do you see your little ones in the gallery? Let us know if you're in the pictures within the comment section below.
