Bloblet

Bloblets are seen in Unreal twice, and in Return to Na Pali only once. In Unreal, both times they are avoidable, in ISV-Kran Deck 1 the player can press a button as soon as the slow doors open and successfully run out of the shielded area with bloblets (sacrificing a few pickups), while in the Mothership Lab they are held under a glass with a forcefield texture, so can be avoided (again sacrificing a few Flak Shells). They are avoidable in Unreal - Return to Na Pali too, but the player must work a little harder to avoid them at that point in Inside UMS Prometheus.

Two groups of bloblets were captured and studied inside the ISV-Kran by russian scientist Tatiana Zimna, who classified them as highly acidic creatures with an incredibly complex genetic structure.

Technical details
In reality, they are made of two actors, a bloblet actor, and a parent blob actor. The bloblet is inactive without a parent blob actor. The bloblet is already offensive but does not attack the player. If a swarm is desired in a map, there must be a group of bloblets, and then usually an inactive parent blob, which can be set to go off at a designated time. The movement of the bloblet is dependent on the parent blob. This system allows the main blob pawn to climb steep surfaces to get to the player.
