For finding and talking about easter eggs in rolling line

With the new weka pass update quickly approaching and with that is coming a host of new easter eggs as well,

franks:

"and if people are wondering about easter eggs...
there's a lot
hidden items, main-layout-style extra scenes, community references, and arguably the most complex easter egg trigger sequence in the game
and of course lots of props to unlock"

Im ready to see what there is to find! and what this "complex trigger" is. HMmmmm.

good luck! as always, post anything you find here, try and be descriptive if you can.
