Their sequence redirectors. They redirect like 307 but in sequence to one another. For example 14002 redirects 14003 and makes 14003 redirect 14004. Then for 21003 he redirects 21004, then 21004 redirects 21005, and 21005 redirects 21010. Why 21010? Let me explain. So all sequencers go in an order like in normal form like a loop. You can basically see the 10th hat in the sprites to see how the sequence goes full on. Sorry if complicated. After the 10th sequencer is done it goes back to 1 arrow.
c2a feel free to band them.
