Google Doodle Celebrates Halloween 2019 With Play Trick Or Treat Game

Thursday’s Google Doodle celebrates Halloween 2019 with cool facts about spiders, bats, and other occasionally creepy creatures. They’re not monsters they’re just misunderstood! In the spirit of Halloween, enjoy some extra trivia treats about these hauntingly cool animals.

Google often celebrate holidays and feast days with their unique Google Doodle, and Halloween is no different. The black, purple and orange Google Doodle for Halloween has been created in collaboration with WWF and is an interactive 'trick or treat' game.

The game enables clients to pick a door, which at that point uncovers a creature. Clients are then incited to pick either “trick” or “treat”. On the off chance that you pick “treat,” you are given a fascinating fact about the creature. For instance, an octopus has three hearts. “Only two pump while I swim, so I prefer to crawl,” the animation advises you.

After clicking the door on the homepage, users are transported into an animated game of "Seven Doors," and behind each door is a different creature that's commonly featured in Halloween-themed movies including an octopus, owl, bat, tarantula, wolf, and a jaguar.

You’ll find them lurking behind the doors of the Doodle ready to jump out, before getting you to choose between a ‘trick’ or ‘treat’. Unfortunately, there are no sweets for those who choose ‘treat’ - instead you will be given a titbit of information about the animal.

Pick treat and you will see a brief informational card educating you about the animal. But if you pick trick, you will see animations of the animals including a black jaguar throwing a basket ball and a snowy owl's head turning into a pumpkin.

Jaguar

Black jaguars, like the one featured in today’s Google Doodle, are actually very rare. Only about 6% of the jaguars in South and Central America are solid black; most are spotted (which, ironically, makes them harder to spot).

Octopus

Octopuses have blue blood. Most animals’ blood is red thanks to a molecule called hemoglobin, which transports oxygen in the bloodstream. Iron gives hemoglobin – and the rest of your blood – the red color that horror movie special effects departments love so much. But octopus blood uses a molecule called hemocyanin to move oxygen around. Because hemocyanin contains copper instead of iron, octopus blood looks blue. That would make for one weird slasher movie.

Owl

Owls can rotate their heads about 270⁰. Imagine being able to look all the way over your right shoulder, then swivel your head around to look all the way over your left shoulder; that’s what it’s like to be an owl. Turning their heads that far would cut off blood circulation to the owl’s brain, but owls have evolved a way to store blood in reservoirs and contract their blood vessels to keep the blood supply moving to their brains and eyes when they’re re-enacting The Exorcist.

Spider

Like cats, some species of hunting spider have a layer of cells in the backs of their eyes which reflects light. It’s called the tapetum lucidum, or “bright tapestry,” and it lives up to the name. If you stand in your backyard and hold a flashlight next to your head at eye level, you may see some surprisingly big, bright green lights gleaming back at you. Follow the lights, and you may be surprised at what tiny spiders those reflections came from! (Try not to worry about the fact that they’re all staring at you.)

Vampire Bat

Only three species of bat drink blood, and they all live in South America, not Transylvania. One (the common vampire bat) prefers livestock, another (the hairy-legged vampire bat) prefers birds, and the third (the white-winged vampire bat) isn’t too picky. They use their incisors, not their canine teeth, to bite into their prey – and those teeth are so sharp that even years after a bat’s death, museum curators have to be careful how they pick up vampire bat skulls, lest they get bitten from beyond the grave.

Wolves

Wolves don’t howl at the Moon; scientists have actually checked, and the phases of the Moon don’t have any impact on how often wolves howl. The extra light of the full Moon may have impacted how often people happened to be outside to notice the howling, though. Maybe humans were the real werewolves all along.

The Doodle additionally links to WWF, where you can become familiar with supporting creatures “like the ones featured in the Doodle”.
