I don't know what that white thing is, it might be a baby slug?
Or maybe it is something useful in making a baby slug?
A few days ago in Shibuya, Tokyo I saw that someone had left their bicycle outside on the sidewalk and there were 2 little dogs in the basket. I was there for quite awhile, but the owner of the bike didn't come back. A few days ago I saw the same thing except it was a baby boy in a bicycle baby seat, but no mother around. This is Tokyo where these sorts of things are generally safe.
These 2 dogs were so patient, just waiting in the basket and watching people as they walked by on the sidewalk.
The dog that is looking at me sure seemed curious. He kept looking at me even as I walked around. I hung around for several minutes. No barking at all and they made no attempts to get out of the basket. I think they have done this before.
The little boy (maybe about 1.5 years old) was just like these little dogs though. He was quiet and content just watching people pass by so probably he was accustomed to this.
