Highway Survival, but I'm a Gluttonous Snake

On the 444,444,444th day after she became a pale-green, three-segment pixel snake, Le Youyou closed her eyes and let her long body fill the 7400 x 4000 screen. Then she slowly opened her eyes and calmly rammed her head into her own 29,600,000th segment.

Familiar death came again. Le Youyou shattered into pieces, but instead of the familiar loop of three starting pixels, she got this:

[The Global Highway Survival World has been activated. Player "Le Youyou," please choose your starting vehicle.]

[Beep beep beep! Warning! Warning! Vehicle selection failed! Loading special vehicle, Snake Express!]

Later, against a soundtrack of other players' despair, screams, and struggles to steal their companions' supplies, Le Youyou bent at a perfect 90-degree angle and kept chomping her way forward.

[ Ding! Absorbed "seamless steel pipe." Length +1. Acquired "Hard" carriage!]

[ Ding! Absorbed "spicy strips." Length +1. Acquired "Chili Spray" carriage!]

[ Ding! Absorbed "megaphone." Length +1. Acquired "Square Dance" carriage!]

A teammate climbed onto the roof and waved frantically. "Hey, Youyou, eat this! I found you a pack of luosifen. Let's make a stinkier, spicier biohazard carriage!"

[Highway Monster]: You people are playing dirty!
