Bell Plant

From Tardis Wiki, the free Doctor Who reference

Bell Plants were a semi-mobile plant from Tigella.

Bell Plants were about human height with a white, tube-like centre. At the bottom were many grey roots which could wrap around creatures. There was also a red, bell-like structure attached to a stem on the top. Unlike other mobile plants, Bell Plants weren't especially dangerous. Though their roots could slow down and capture, they didn't have any noticeable weaponry and just bludgeoned the intruders with the bell-like structure.

Romana II was attacked by Bell Plants but managed to free herself. She misled a Gaztak party through the plants so that they were attacked. They also managed to pull themselves free. (TV: Meglos)
