Transparent Panel in Pipeline Room Pipeline

Jamie points to this transparent panel set into the Pipeline Room's pipeline wall, drawing the Doctor's eyes to unnatural foam buildup signaling the sentient weed's rapid expansion. They watch the foam swell and the weed grow uncontrollably through the clear surface. Pressure fractures the panel; foam erupts into the room as a tentacle bursts forth, seizing an engineer and dragging him into the biomass amid shouts for retreat.
