Silicon Valley is feeling festive this Halloween, with tech companies offering treats like a mummy T-Rex skeleton or a Rolls-Royce ride with an otherworldly passenger. Here's some of the ghoulishly good fun from Google, Amazon and more.
Hitch a Lyft ride with the Headless Horseman
Riders who dare to order a car through the ride-sharing service Lyft on Halloween night could end up rolling with a supernatural passenger.
Lyft customers in New York, San Francisco or LA who ride from 6 p.m. to 11 p.m. could be picked up in one of three vintage "ghost cars" prowling each city. They'll score a free ride, receive Halloween treats and .... oh yeah, sit beside a headless horseman.
The ghost cars -- which include a 1933 Rolls-Royce Phantom and a 1961 Bentley -- and their spooky passenger are a stunt to promote the show "Sleepy Hollow" on Fox. Don't live in one of these three cities but still want to get your double-H fix? Check out #SleepyHolloween on Twitter.
Mummified dinosaur at the Googleplex
Some companies let employees bring their pets to work. Google has a pet T-Rex skeleton named Stan, who's a famous fixture at the Googleplex in Mountain View, California.
Though Stan is already a festive bag of bones, he still got decked out for Halloween. Googler Louis Gray posted a snap of Stan the Mummy on his Google+ page: "Considering the T-Rex's age, and our association of mummification with more ancient times ... this works."
Download $115 in spooky Amazon apps for free
Amazon is treating customers to $115 in paid apps and games, available for free download through November 1. The trick: You'll have to download Amazon's Appstore for Android first.
The pack of 40 free apps includes classics like Sonic the Hedgehog, steals including the human anatomy atlas Visible Body (which usually costs $30) and Halloween-themed games including V for Vampire and Plants and Zombies.
Yikes! Check out awful costume #Pinfails
Projects on Pinterest often look easy and fun, but they can go horribly wrong when regular ol' folks attempt them. Even Pinterest itself can apparently poke fun at a good #Pinfail, as the company put together its own pinboard of unintentionally scream-worthy Halloween costumes (check out the deformed Bert and Ernie that aren't meant to be scary!).

Slackers only: Postmates will deliver costumes on demand
If you're reading this and you STILL don't have a costume ready, Pinterest projects might be too scary to undertake now. So for you, super-slacker, delivery service Postmates will deliver costumes on demand in San Francisco, New York City and Chicago. But Postmates has been delivering the costume goods all week and there's no guarantee you'll find your top choice in the costume section of the app.
So if you end up on Pinterest's #pinfails board, there's no one to blame for the horror but yourself.
