Pattern Help for Baby Blanket Edging

I can’t seem to wrap my head around the edging pattern I have for a baby blanket. I’m sure it’s quite simple…but I seem to be having brain freeze. Any help would be appreciated. The pattern goes as follows (from Row 3):

Row 3: K1; *work 5 sts in next st, turn; P5, slip next st, turn; K2tog…

what does it mean “work 5 sts in next st”??

Welcome to KnittingHelp!
This video shows the 5sts in one, the turn and p5. From there on it’s different but you can continue with your own directions. It sounds like a bobble on the edging?

Thank you for the help and the video…now it suddenly all makes sense. The patterns says it’s “shell edging.”
