Suckweed

The Suckweed was a species of plant native to the savannah of Flux. They were similar to giant cacti, with buried spines which would shoot out when prey walked over it. Due to the harshness of their habitat, Suckweeds could wait for hundreds of years for food to arrive and could last as long without water.

When Flux was recreated on Planet 1, robotic versions of Suckweeds were added for effect. The Semblance of Draxyx was killed by one when they were reprogrammed into thinking that he was threatening Sebastiene. (TDA: The Doctor Trap)
