Gulrot, Unclean
From Destiny 1 Wiki
Gulrot, Unclean is a Hive Ogre locked away in the Prison of Elders. He was created by the Worm Keepers out of desperation, a group of Wizards who lacked the resources to do a proper summoning.
Gameplay
Like Phogoth, Gulrot's weakspot is its exposed heart on its chest. Gulrot has all the standard Ogre attacks. What makes Gulrot especially dangerous though is that every couple of minutes, Gulrot will pour bile into the air (this is preceded by the message "Gulrot's stomach gurgles and churns"). This has the effect of slowing down Guardians to a standstill, similar to the effect of a Web Mine explosion, except on a much slower scale.
