Monster Engulf Attack and Movement

[Morbius X]

Scouring through the boards, FAQs, and Google on both D&D 3.5 and Pathfinder systems, I cannot find anything clarifying one important question about the ENGULF special attack.

Once a creature is engulfed, and stuck inside (in Pathfinder's case, the creature is pinned), can the creature continue its actions as normal? Can it continue to engulf more enemies if it can?

For example, I had 3 of my players face a Gelatinous Cube. It engulfed them, but captured only one. That player was pinned inside (and I assume it would only be able to escape if it escaped the pin and grapple versus the ooze's CMB?).

With the PC pinned inside, is the Gelatinous Cube able to take its actions normally such as move its speed and slam attack or try to even engulf more PCs?

Yes. It can totally engulf more PCs. I demand it.

Gelatinous Cube's Engulf wrote:

Although it moves slowly, a gelatinous cube can simply engulf Large or smaller creatures in its path as a standard action. It cannot make a slam attack during a round in which it engulfs. The gelatinous cube merely has to move over the opponents, affecting as many as it can cover.

(Emphasis mine)

Also note, there are creatures with an ability that's called Engulf, but that doesn't use the standard Engulf rules.
Gibbering Mouther and Shoggoth's Engulf ability works more like Swallow Whole, doesn't Pin the target and they can cut themselves out.
Basically, they REALLY REALLY shouldn't have used the name Engulf, but they did, and we can't do anything about it.
Just mentioning it because it's so easy to overlook or get totally confused over, if you don't realize that they aren't really Engulf at all even though they share the name.

I see. Ok. Then the way I ran the combat worked. One player had his character engulfed and while stuck inside, I had the gelatinous cube on its next turn move and try to engulf another foe. Just wanted to make sure that was legit.
