What if dogs can have the ability to dig? If you have a tamed dog you press on a tile and then you can say „dog dig“. When there’s a big rock, it digs up the rock. When there’s a row of potato it digs up a potato. When there’s a stump, it digs out the stump. Empty clay pit / empty reed… you get the clay / adobe. When there’s just ground it digs a hole (3 more times and it’s a grave). When it’s on a tombstone it digs out the flat rock… and so on. It is still expensive, cause you need to have a loyal dog, but it could save some shovel uses. And dogs are even more useful this way.
Also when a schnauzer digs for hidden treasures, it would be nice if the dug out blueberries can be replanted somewhere else and don’t vanish at all
