Bulb (The Mutant Turnip)
From Tardis Wiki, the free Doctor Who reference
Referred to as simply an alien ‘Bulb’ by the Eleventh Doctor, the bulb had burrowed underground on a French farm. There it had feasted on the soils nutrients and grown to a huge size. Its powerful roots drilled through the soil, attacked those above ground and pulled them under. The bulb was shrunk by a particularly bad batch of Michel’s wine belonging to farmers Alain and Simone. The Doctor removed the shrunken bulb to be rehoused somewhere out of the way. (DWA: The Mutant Turnip)
