Since Etho first created Wilson in his survival LP, I've had this virtual pet in my world, although I've updated him over time with new blocks or redstone devices. And it is by no means as complicated as his Redstone.

I thought people might be interested in having a look at how to build one yourself and look after it!

I'm not a redstoner, so im more than sure it can be done better, but it works :)

Includes:
  Feeding
  Randomly sick
  Random healing (this means it has a chance to heal sickness when given food)
  Healing
  Note blocks
  Lots of randomisers
  Togglable levers to turn on and off certain features
  Dynamic smile! (his smile goes away when he is hungry!)

I have signed everything so you know what parts of my Redstone spaghetti does

Hope you like it!
