Bell Plant
From Tardis Wiki, the free Doctor Who reference
The Bell Plant is a semi-mobile plant from Tigella, briefly seen in Meglos.
The Bell Plant is about human height with a white, tube-like center. At the bottom are many grey roots which can wrap around creatures. There is also a red, bell-like structure attached to a stem on the top. Unlike other mobile plants, Bell Plants aren't especially dangerous. Though their roots can slow down and capture, they don't have any noticeable weaponry and just smack the intruders with the bell-like structure.
