Just a couple of Lesser Spleens, the first of which isn't necessarily, completely, absolutely a Spleen, but being a particularly foul-tempered and savage animal with abnormal tendencies, it's borderline Spleen so it's going in the big bag with the others...
The Acanthothere, commonly found in arid savannah and desert regions, doesn't like you. It doesn't much matter who or what you are, it doesn't like you. They don't even much like each other and when packs of the reeking things attack you, one or two of them are almost always liable to get into fights with each other over who gets to pull your head off.
According to the Acanthothere Owner's Manual, you should never, under any circumstances, ever, own an Acanthothere, because it will instantly try to kill you. Which rather renders the whole concept of a handbook for them more than ordinarily futile.
The Acanthothere Owner's Club, which has precisely a quarter of one member (and that's diminishing rapidly) has long held the coveted "Most Pointless Organization In History Award" for the last two centuries.
And another nasty, rubbery whassname thing... a really unsightly, armpitly ugly freak, this one...
The Rakbeast is hideous, and not just at an amateur level. This stenchbucket is professional, epic level hideous and has completed a ten year course of Being Hideous Master Classes with honours. It holds a full Doctorate of Hideousness from the University of Hideous and comes complete with a chromium-plated, fully-illuminated, genuine accessory Certificate of Hideosity.
(I know there's no such word as Hideosity, you know there's no such word as Hideosity, but IT doesn't know that... and it's best not to enrage one of these things or it'll start coming on all hideous at you.)
The Rakbeast often enters International Hideousism Competitions, and has for many years held the 500 Metres Being Hideous Race title and took gold at the 2008 Hideolympic Games in all events relating to being hideous. Aside from being hideous, it's also a savage, homicidal Spleen like all the other savage, homicidal Spleens, etc, etc.
And it's hideous too.
