Bugger, I have a nasty suspicion I forgot to change the Skills to reflect the removal of the Pureblood.
Just let me check:
Gu'en-Deeko: Athletics +6, Perception +3
Gladiator: Athletics +10, Intimidate +5
Bugbear: Stealth +6, Survival +2
Drow: Perception +2, Stealth +4
Yes, I forgot to remove the Deception +6.
It should have Skills: Athletics +10, Intimidate +5, Perception +3, Stealth +6, Survival +2
Also, its languages need changing as it loses the Pureblood's Abyssal and Draconic and gains Elvish and Undercommon.
So it should now have Languages Common, Elvish, Goblin, Undercommon (all from Brain-Eating)
Updating the Gu'en-Deeko Fighting Ape.
