Disguised Cuttlefish Remnant

A small cuttlefish, no larger than a human hand, rests unmoving on the swamp mud. Romana reaches out to touch it, her expression shifting from confusion to dawning realization as the Doctor explains how this creature’s cellular regeneration provided the template for Kroll’s colossal, temporary form. Its presence marks the final unraveling of their deception—the same biology that let Kroll tower over the swamp now lies dormant, exposed.

S16E20 · The Power of Kroll Part 4
Krolls transformation revealed in swamp

The normal-sized cuttlefish serves as the climactic physical evidence revealing that Kroll's massive form was a temporary biological deception. The Doctor identifies its cellular regeneration as the mechanism that allowed Kroll to absorb the fifth segment and High Priest, transforming them both into the planet's menacing consciousness. Romana's recognition completes the biological puzzle.

Before: Lying dormant and unnoticed in the swamp mud
After: Examined and explained as the source of Kroll's transformation, left in place as the scene transitions away

Before: Dormant and inconspicuous fragment lying exposed on the swamp surface
After: Scientifically interpreted and discussed by Romana and the Doctor, no longer a threat
