It would be really cool and then digging wouldnt be as boring. There needs to be more interaction with the beaches/digging.Such as collecting hermit crabs with a bucket or something.Another can be seaweed washes up on the beach and you can collect it or destroy it for money and if you walk on it it slows you down.Also random trash washes up from the beach like,surfboard,wakeboards,beach balls(volleyballs etc.),trash obviously,buckets,shovels(broken/non broken), and other random junk.Its just an idea since you brought up digging. Still like your idea tho
