the one on the left is a Sandyeti, while it looks like something captain kirk would fight on the old star trek don't be fooled it can rip your face off in a split-second, as you can see it has no eyes and it smells it's prey and once it's got your scent you better run like hell. The one on the right is a Jumperroach there nasty little buggers that steal anything and scare other animals and would-be travelers with there skull like faces not to mention they walk on 2 and 4 legs and jump really high to get away hence the name "Jumperroaches"
