The worst pure slimes with negative effects are: Tangles because they can grab plorts with their vines Dervishes create cyclones when left unfed Crystals create crystals on the ground which can make short work of your health Quantums teleport when agitated Rad aura poisoning speeds up when you're in multiple auras

I'd say any combination of these would be fairly interesting. Quantum Rads are more annoying than a threat because their ghosts emit "fake" auras which can throw you off.
