In StarCraft II, what is the name of the Zerg queen's ability that creates a temporary Creep Tumor?

Spawn Creep Tumor is the Zerg Queen ability in StarCraft II that creates a temporary Creep Tumor.

A Queen uses Spawn Creep Tumor to place a tumor on existing creep. The tumor then spreads creep outward, allowing Zerg structures and units to operate across a larger area. Creep also improves the movement speed of many Zerg ground units, so expanding it is both an economic and military priority.

Creep Tumors can create additional tumors, producing a chain that gradually extends Zerg territory across the map. They are hidden while burrowed, but opponents can remove them with detection and attacks. Because tumors are temporary battlefield objects rather than ordinary combat units, their placement and protection require careful attention.

Spawn Creep Tumor is different from Spawn Larva, which increases larva production at a Hatchery, and Transfusion, which restores health to a friendly biological target. The names reflect separate Queen functions.
