Boo is one of the less interesting members of "Stompin Stuff". He has no really interesting history, and the personality of a mountain goat. As he is not very bright, but very persistant and seems not to mind the abuse, he was selected by the Blood God to be what the four knights call "Knuckle-Fodder". He doesn't seem to mind this as he is too dull to really comprehend the position he is put in, he is just happy to be paid to ram into things. Rumor among the CHaos Cultist fans is that this is all just an act and he wants to sacrifice himself for the Blood God on the pitch. Boo has neither confirmed nor denied these rumors. In fact when asked about them, he just stared blankly at the Nuffle announcer and chewed on a piece of someone's shoulder plate that was left on the pitch after their first game.
