Strange Tree

The TARDIS exterior takes the form of a gnarled, peculiar tree in the prehistoric forest outside the tribe's cave. Flames erupt from the Doctor's fingers on arrival, alerting Kal who finds him there. The Doctor scans its branches urgently during captivity, pleading for return as escape route. Tribe members circle with suspicion and awe; Kal recounts the fiery reveal to undermine Za amid survival struggles. After cave escape, TARDIS lands nearby again. Doctor checks monitor showing strange trees; radiation meter spikes to danger zone, hinting at Orb's influence or volcanic threats. Shadows rustle with tension, amplifying group disorientation and peril.
