Earlier this month Cartoon Network quietly released a mysterious new short entitled Infinity Train online. Within days of being released the short went viral in the online community, with fans of Steven Universe, Adventure Time, Gravity Falls, and Over the Garden Wall all praising the show and hailing it as Cartoon Network’s next big thing.

The short episode follows a girl named Tulip and her small robot companion as they make their way through a seemingly never-ending train with cars full of puzzles and worlds unlike anything she’s ever seen. The short shows a glimpse of a complicated, well thought out mythology with the potential to be the start of something much greater.

You can watch the short here:

Not much is currently known about this short episode, but speculation is that if it does well enough online, Cartoon Network might opt to turn this into a series. With the end of Gravity Falls earlier this year, and Adventure Time ending in 2018, fans will be looking for a new mysterious show to speculate about and Infinity Train looks like it could fill that gap nicely.

What did you think of this short? Would you like to see it become a series?
