This feature allowed you to transport yourself through connected hoppers.

It was a precursor to soul conductors but less cool and much less efficient.

History

0.4.0X

Poppers, short for player hoppers. To put it simply, this feature was dumb and it sucked.

0.3.0+

This was a very fun feature to test. Basically, players can now jump in a hopper and be transported down the chain, unless it’s blocked or too long.
