Well, not really, but close.  The detail in this thing is flat-out amazing.  You'd certainly be frightened if you woke up to one of these things sitting on your bedroom floor.  Just one quick point though, the piranha plant is quite possibly the stupidest of the bad guys in Super Mario Bros., all you have to do is stand on the pipe and they can't come out.  Why is that? The damn thing should be able to pop up and eat you. 

This thing is so realistic that, quite frankly, we're a little bit frightened it might come to life and start breeding. 

The artist even included a little “Making Of” video to show you how he got it accomplished.
