"Creatures of Habitat" is what Sean Kenney calls his display, now at Utah's Hogle Zoo.

But your kids are more likely to call them "those really cool animals, made out of Lego blocks."

Kenney says all of the 30 animals he's constructed -- including polar bears, monkeys, frogs and penguins -- are endangered.

The display -- on loan from the Philadelphia Zoo -- will be here, until September.
