critters

>A creature with the head of an opossum, the body of a wolf, and the ability to spit venom.  It is immune to poison.
>A creature which looks like a moray eel, but covered in scales and eyes, and with legs like a millipede on its underside.  It is 30 feet long and can spit out smaller versions of itself (about the size of a normal moray eel) in large numbers.
>A massive, egg-shaped entity which floats a few inches above the ground.  Its shell is selectively permeable, allowing it to absorb things through it or harden to act as armor as it pleases.  After absorbing a large amount of matter, it will stop and separate into two of itself, each the same size as the original.
>A creature shaped like a human molar, with the roots of the tooth being large blades and having little legs sticking out of the ``top'' of the tooth so that it's like an upside down tooth and it has a mouth on the underside.  THe entire thing is covered in scales and it can secrete acid.
>A ball of jumbled objects shaped like a "T".  It is sharp to the touch and can shred things as it rolls around.
>A V-shaped, fur-covered creature with ridges on the edges, some tiny legs which fold up into its body, and no other features.  It can launch itself through the air and spinning-glide kind of like a boomerang, which it does in order to attack.
>An amorphous green transparent blob which causes any text or other communicative symbols it covers to be readable by anyone who looks through it.  Found in ancient ruins and kept as an essential tool of many explorers and archaeologists.  Killed by extreme heat, extreme cold, and some radiation.  Does not like bright lights--those can harm it, too.  Kept in clay jars (glazed inside) and must be fed mosses and lichens and agar to keep it alive.  It cannot digest flesh.
>A swarm of flying, triangular, two-dimensional objects.  They can pass through solid matter if they arrange themselves so that their edge is facing what they wish to pass through and can cause massive damage if they turn while inside something.  Potential spells can add a dimension, rendering them to be inert pyramids (triangular base; 4 sides rather than square base; 5 sides), while limitation spells can take away a dimension, obliterating them entirely.
>Tall humanoid with head like a starfish.  No hands or feet--simple stubs instead.  Pale, featureless body.  Sometimes wrapped in black cloth.  Can consume dreams by sucking on a sleeping person's head with its own head.  Appears in the person's dream when doing this, and can be knocked out if killed or incapacitated in the dream by the dreamer.  If multiple of this creature are sucking on dreamers' heads, they may touch to join the dreams together.  When doing this, they may merge into one, more powerful entity within the dream.  Ultimately harmless, usually.  May drain a few experience points or rob you of restful sleep, but they will never kill you.
>A flat creature which can turn one side of its body into a hole which is bigger on the inside.  Disguises itself as regular holes in the ground or caves.  Tries to digest things that fall inside.
>A rope that hangs with four loops like it's tied in a bow at the end.  Ensnares its prey and attempts to squeeze the life out of them.  The loops are able to break off and grow into more of this creature.
