We've got one, have you? Ours comes with various parts but only one nose. We lost that nose for a while which was quite disappointing. It was good when I found it again though.
If I remember correctly you just used to get the parts and you used a real potato as the base. You get supplied a faux-potato now.
Also spud guns were good weren't they? Do you still get them?
What about white dog poo? Anyone seen any? Marckee?
