Niffler

There is a creature in Harry Potter that is called a Niffler. It is attracted to shiny things such as gold and diamonds and jewelry. My kids and I thought it would be a great mob on Minecraft that you can tame similar to how you would tame a wolf. If tamed, it could burrow and bring you diamonds, gold, emeralds, etc. Ya know, shiny things. I think it would be good as a mob that is harder to tame, like you use iron to tame it, but maybe its a 1 in 10 chance you succeed or something to that effect. And the items it brings you are typically lower value such as iron, or gold. but occasionally higher value such as diamonds and emeralds. The niffler looks similar to a platypus. As a side note, a platypus would be a cool mob too. And you could use its venom to make poison arrows or potions and such.
