Sinestro Crops - Tri-eye

I googled this

Traveling across it's planet via a system of connected underground tunnels,
Tri-Eye lives at the bottom of waterwells, springing up and capturing its prey
when they come to take a drink. Once in its grasp, Tri-Eye's three mouths will
tear through flesh and bone, leaving no trace of its meal behind.
Tri-Eye liked to attack Green Lantern Corps members directly and feast on them
while blasting his way through more. He then returned to Sector 3145 following
Sinestro's capture. Tri-Eye was later captured by the Green Lantern Corps
and placed in a Sciencell on Oa but has since gained his freedom and rejoined his Corps.
