Scroll to the bottom of chat.heyatli.com before November 2 and you will meet a few visitors that were not there in September. A fuzzy spider dangles from the top edge of the page on a single thread, blinks every few seconds, and jumps if you point at him. A sheet-ghost peeks out from behind the big phone near the top of the page, leans after your cursor, and ducks out of sight for a second and a half whenever the pointer gets close. Down in the footer, a carved pumpkin blinks beside a lantern that throws a flickering pool of warm light onto the paper.
Between them sits a pumpkin sticker. Clicking it flips the lights off and opens Atli after dark, a secret night-mode gallery where Atli tries on 40 Halloween costumes at once.
How to find the secret door
Six costumes from the gallery spend Halloween week out on the main site. The Web Developer hangs from the top edge of the home page. Boo hides behind the big phone. Do Not Disturb, a sleepy bat, perches on the corner of the “Ready before you fly” stamp. Every so often, Night Shift flies across the top of the help centre on a broom trailing four-point sparks. Down at the foot of the home page, Jack and Will-o’-the-Pumpkin guard the pumpkin sticker that opens chat.heyatli.com/boo/.
None of the home-page visitors get in the way of buying a plan. Every piece is decorative, carries no text, and sits clear of the buttons. If your phone or computer is set to reduce motion, the whole cast stays still: no swaying, no blinking, and no cursor chasing.
Explore the 40 Halloween costumes
Step through the pumpkin door and the daytime cream paper flips to deep midnight indigo under a crescent moon and eight twinkling stars. A tilted stamp at the top sets the house policy: “Museum rules: eyes yes, pockets no. 🎃” Right-clicking or dragging the Polaroids is turned off, though the dealer at the top will gladly print you an official souvenir card to keep.
All 40 costumes are travel, hotel, and telecom jokes dressed up for October 31. Ten of our favourites from the wall:
| Card | Costume | Caption on the Polaroid | What happens when you watch |
|---|---|---|---|
| 01 | Jack | Locally grown. | Blinks from inside the carved pumpkin. |
| 02 | Boo | The classic. Two eye holes, full bars. | The lower half of the ghost sheet sways while his head stays still. |
| 11 | Late Checkout | Checked in 3000 years ago. Still wrapped up in it. | Holds a 3,000-year wink through the bandages. |
| 14 | The Medium | Every cup comes with spirits. | The three little steam-ghosts rising from the teapot fade out while you look. |
| 17 | The Headless Roamsman | Lost his head, kept the connection. | Carries his own smiling head under one arm and a jack-o’-lantern in the other. |
| 26 | The Deadline | Comes for expired data plans. | Floats straight up and out of his own Polaroid, leaving an empty white frame. |
| 27 | The Watcher | Sees every coverage gap. | After a short beat, every eyeball on the suit snaps to stare directly at you. |
| 31 | Dr. Gigahertz | Do not drink the green one. | Shakes the bubbling green flask once, which immediately turns the potion red. |
| 36 | Not Spooky | Refused to change. Respect. | Wears a fluffy panda suit and blinks calmly among the monsters. |
| 40 | Room 13 | Checkout is at never o’clock. | Wheels his brass luggage cart completely out of the frame. |
Half the jokes come straight from life on the road. Sir Hotspot (“Runs hot. Literally.”) and Sir Lag-a-Lot (“Sworn to guard the hotspot.”) exist because tethering a phone in a warm train carriage warms your pocket in ten minutes; if you are sharing a connection on a trip, our eSIM hotspot guide covers how to keep both battery and data under control. The Count (“Counts megabytes, mostly.”) and The Deadline are a nod to anyone who checks what is left on a plan by typing data or usage in the chat; see how to check your eSIM data usage.
Meet the 22 animated Halloween portraits
Eighteen cards on the wall behave like normal photographs and give a small poked-doll jiggle when tapped. The other 22 are living portraits. Point at one with a mouse or tap it on a phone and the illustration wakes up for as long as you watch, then resets once you look away.
Two of them leave their own photographs altogether. Watch The Deadline for a moment and the tiny grim reaper drifts upward at a slight tilt until the Polaroid is completely empty. Watch Room 13 and the ghostly red bellhop finally performs the checkout he has been putting off, rolling his vintage suitcase and brass cart out past the left border of the card.
Several others play with comic timing. Dr. Gigahertz gives his bubbling flask a nervous shake right before the green potion turns bright red. The Watcher pauses for a beat before every cartoon eyeball on his suit snaps its pupil toward you while Atli’s own blue face keeps smiling straight ahead. Annabelli (“Found in the hotel wardrobe. Do not make eye contact.”) leans slowly forward from her feet while tilting her head. Lights Out (“Appears when your screen goes dark.”) takes two small breaths and swells until his shadow fills the entire Polaroid and only his glowing eyes and grin remain.
Pull a card, share it, or save a souvenir
At the top of Atli after dark, the “Who showed up tonight?” dealer picks one costume from the closet for you.
Clicking Save card turns your costume into a souvenir card. The Polaroid sits at a slight tilt on a night sky with a crescent moon and six diamond stars. You can save it as a square Post or a vertical Story. And once you are ready to head back to daylight and sort out mobile data for your next trip, our guide to buying an eSIM on WhatsApp walks through the daytime version in five steps.
