# obj

There are two types of movable atoms: objs and mobs. The difference between them is that a mob can be attached to a human player, and is also typically used for NPCs and creatures. The obj type is a little bit simpler and is typically used for objects in the environment, items in inventory, etc.

Objects are derived from `/obj`, which derives from `/atom/movable`.

The following example defines the obj type `/obj/scooper`.

```dm
obj
  scooper
    desc = "Super pooper scooper."
```
