Okay, first off: This isn't about how "all the 'monsters' look copmletely retarded"; I'm not even going to judge how they look.
This is a suggestion on how the monsters will attack.
Say the fluff just tries to nibble at your toes (oh, horrors!); doing minimal damage, or maybie trying to... er, jump on you to death?
Or the OMG. They say it's "A nasty piece of work". So, why not make it a nasty piece of work by having it leap at you, or maybie lash out at you with its tail, or maybie bite you (and I mean real biting, folks, the "tear your legs off" kind of biting).
Or the garlic; it's... er, regurgitations having a range of distances.
And maybie the clutch can come swooping down at you; and flying up well out of your reach, and you can only kill it when it's trying to attack you.
Lots of possibilities.
Haijin is thinking that the Garlic will burp out noxious green gas that will hurt you if you touch it, and the Fluff will just bump into your legs a little. Haijin figures it's sort of like a Magikarp but more weathery. heart
