The pertinent part of the spell description for Stinking Cloud that has me curious is:
Each creature that is completely within the cloud at the start of its turn must make a Constitution saving throw against poison. On a failed save, the creature spends its action that turn retching and reeling.
Now, obviously the creatures will need to fail their save in order to be affected. And, also obviously, their action is consumed with "retching and reeling." But what about their movement?
Are victims of the spell Stinking Cloud able to move out of it?
