Visual and tactile. Most likely is malleable, but this word has no such implications inherently; porousness or foaminess is likewise not implied. Might also include "cushiony", "cotton-like", "wool-like"; a fractal nature might be present. For fuzziness: not necessarily hairy or furry, but must be soft; not bristly (which implies stiffness and hardness). See also: ranti, rufsu, xutla, panje, dilnu, mapni, sunla, fonmo, jduli, pesxu, marji.
