Thanks for the comments! I had a little extra spare time and thus I finished a badger and a tree (Gamma World PC's).

Finding reasonable mutant plants is rather hard - I've got a couple from CP Models and Ral Partha (checked Ramshackle games and couple of other manufacturers), plus the Fungoid from Mirliton, but still...
Just to note that bases will receive some grass and stuff, but I'll finish them when I have more models painted (it's messy).
