What creatures give out resources?

[Ungod]

And how does that work?

[Pipstickz]

Level 2 Grasans, if given certain names specific to each output, will consume 1 wiiya per day and excrete one per day of various resources (fat, skin, solid stench, toxic gas, grasan ferment)

A Molima, if left with its default name, will consume as many bones as ten times its level (10 for level 1, 40 for level 4, etc) per day and produce one death spore per day

An Elucubration will consume one candy per day and produce one coloured paper per day (I don't think their name matters in this case, though I'm not sure if they're even nameable either)
