The fourth episode of the Star Wars Roll Out animated shorts series is called "Chewie, the Porgs, and the Sea Monster - Chapter 1". It premiered on YouTube on August 30, 2019.
BB-8 and a Star Wars ball lead the opening credits sequence. They are followed by Rey, Maz Kanata, Finn, Captain Phasma, a pair of stormtroopers, Ben Solo, Han Solo, Chewbacca, and a trio of porgs.
The Wookiee, Chewbacca, is relaxing peacefully on an island located on Ahch-To, when some annoying porgs rouse him. They attempt to feed him a plant of some sort, which he clearly dislikes, despite being hungry.
Chewie, now awake, decides to try his luck at catching some fish for a meal. However, the porgs remain fixated on him, perching on him as he waits for a fish to take the bait. Instead, he only manages to pull up an old boot, which the porgs then attempt to snatch. This greatly irritates Chewbacca, who forces the birds to retreat into the ocean, where they easily locate small fish and taunt the Wookiee with their catch.
Realizing that his previous attempts have been unsuccessful, Chewbacca gets ready with a trident and a rebreather before diving into the water to find the elusive fish, hoping to finally satisfy his hunger. The porgs also try to follow him underwater, but Chewie manages to shake them off in a kelp forest.
Chewbacca stabs a fish resting on the ocean floor with his trident. The fish immediately turns red and tries to escape, unaware that the Wookiee is holding onto his weapon and allowing himself to be dragged along by the sea creature. The fish then crashes into a rock and dies, coincidentally waking up another sea creature that had been sleeping in the same rock.
Chewie leaps out of the water to celebrate his successful catch, and for a brief moment, he even feels a tinge of sadness that there are no porgs around to share the moment with him. However, the awakened creature uses its light-bulb to hypnotize the Wookiee before dragging him back underwater, now encased in a purple bubble that appears to keep Chewbacca in a state of stasis.
Unbeknownst to Chewbacca, who is once again at rest, the creature carries him to the lair of its much larger relative. This larger creature uses the purple bubble, filled with various sea creatures, as a food storage, hinting that it won't be long before Chewie becomes its next meal.
