tle says it all. Wouldn't you love to grow a little Mushroom or Cactus pet? Think of the possibilities for mutations too - Venus Fly Traps, Poisonous Mushrooms, etc.
It would also be cool if some of them changed with the season - like a deciduous tree that flowers in spring, fruits in summer, turns gold in fall, and loses its leaves in winter!
Bring on the leafy babies!
