It’s a complete cow (you can see its whole body), with something next.A cow with appended data is still valid cow.

If our cow swallows a microSD, it’s still a valid cow!Even if it contains foreign data, that is tolerated by the system.

A farmer was denied permit to build a horse shelter,so he builds giant table & chairs which don’t need a permit.
