A zoo in Louisville, Kentucky has decided to augment its collection of live animals with 23 fantastic Lego sculptures created by renowned Lego builder and children’s author, Sean Kenney.

Using more than a quarter of a million bricks (464,770, to give the precise number!), Kenney’s sculptures range from just 12 inches to a massive 8 feet tall, and include a gorgeous Monarch butterfly (39,000 bricks), a 6-foot-tall hummingbird display (61,107 bricks), a life-size peacock (68,827), bison, and more.

Check out more photos, a video, and details of how to visit below:

The exhibition runs from today through July 5. More details can be found on the zoo’s official website.
