The search engine site, which sometimes uses its homepage to honor prominent figures and days, is celebrating the spooky holiday with an interactive game.

To try it, push the play button on the graphic. A row of homes will appear, and you’ll be prompted to click one of the doors.

Once you select a door, you’ll spot a Halloween-related animal, like a tarantula, bat, black jaguar, octopus, snowy owl or gray wolf.

You’ll then have the option to “trick” or “treat.” If you choose “trick,” an animation of the critter will play. If you go with “treat,” you’ll learn a fact about the creature.

The Google doodle is in collaboration with the World Wildlife Fund, an organization that strives to "protect the future of nature," its website said.

You can "adopt" one of the six furry friends when you purchase a $55 adoption kit, which includes a toy of the animal, photo, certificate, species card and gift bag. All process will go toward the brand's conservation efforts.
