Grimbly 

Just a little green guy. They thirst for blood and when given thickening powder from Walgreens they devour it and start to chulk

The grimblys bit holes into his skin, trying to burrow and drink the blood.

grimbo 

combination of two words: Grim, meaning ugly. And Bimbo, meaning a girl with loose moral character and less than average intelligence.

I drank twenty beers last night and woke up with some horrible grimbo next to me in bed.

Grimbot 

A robot that is either; a)hideous in nature or appearance; or b)not working properly. Malfunctioning.

That ugly silver thing you got to vacuum the floor, is a total grimbot.

An example would be the robot from Lost In Space.

Grimbo 

Grimbo is a half naked, albino, starved until the verge of death, and put in a cage until needed for slave work type of being. Grimbo can not be defined as anything near human, as it is the exact opposite. Grimbo has no indentifying features such as a micro-penis, etc. etc. There is one way to identify a grimbo, though. It will make a high or low pitch screeching noise quite often. You can tell what emotion or physical state a Grimbo is in by this chart:
Content: Oroororororor
Mad: oooor OOOROROROROR
Sad: orrrrrr orrrrr orrrrr oooorrrr orr
Fearful: OREROEOEREEIEOEEOOR
Confused: ororr... ororororrorOroroO...
