Outstanding, I knew it was probably a small oversight that I just wasn't aware of. And I also set the maxStack size in the appropriate location. Thank you for pointing that out to me. My last question with these grenades seems to be how I cast the entity. I cast it too Living base and it works, but I don't think Minecraft likes that. How should I alter the code? Here is the rather obvious error lol: http://pastebin.com/1H0wQyBV
And here is my entity class:

Once again I apologize for how noobish I sound and how obvious these errors are but I really am trying to learn and I would rather learn correctly, rather then let the errors sit there since the item works as is. Thank you again.
