Picture book from 90s, Native American/ First Nations (?) legend about three girls in danger for staying out late, blinded by tree sap, rescued by their younger brother

This was a picture book read to me in California in 1998. I can't recall what group it was concerning, but I think it may have been set in the Pacific Northwest or perhaps along the Canadian coast, but it may have been set near a Great Lake. I don't remember any of the pictures clearly, but I don't think there were very many, and my impression is dark/muted colors.

The story was that three sisters disobeyed their mother and stayed out late playing on the beach at night. They had been told if they did that, the \[some kind of giant or creature, I don't recall the name\] would get them. They were then snatched up by that creature, large enough to carry them in a sack. They tried to climb out of the sack as they were being carried through the forest, but the creature used tree sap to keep their eyes closed so that they couldn't get away or try again.

Their mother, heartbroken, wandered by the shore looking at their footprints and knew they had been taken. A young man appeared in the story at this point (he either washed up from the water or was in her house when she returned?) He told her he was her son (he had either grown up very quickly or had not yet been born. He make have come from a shellfish?) and he would go rescue his sisters. He made it to the creature's home, which I believe there was a picture of, it was just one large room where the three girls were tied up.

I don't remember how he saved them but they all got home together. Presumably at the end the girls promised not to stay out late again.

I'd love to find this one again so I can remember how exactly it ended!
