Pola was a Vulcan boy who lived with his family aboard the USS Enterprise-D.
In early 2364, together with Matthew, he managed to sneak into the observation lounge of the ship and brought some toys with him.
William T. Riker knew Pola and Matthew, and rushed them out of the room, when a meeting was about to be held there, but one of them forgot a Chinese finger trap on the large table.
Later, when the Enterprise-D was without energy, Pola was in one of the quarters. (TNG: "The Last Outpost")
