Did you get the Turtle Cap from Nubbinator?
If yes how much was it and where are they sold 
It did, it was $4.50 (basically materials cost for me) and no more have been made or sold outside of the two I did.
I think they're from the LEGO figures. Pop their heads off and stick a stem on the bottom. 
It's a little more than that since the stem is too big for the hole, but yeah, that's the basic idea.
Its like when I was younger and I asked my dad if you could squeeze a small block chevy motor in a little car.
His response was "with enough time and money anything can fit."
Hot rod magazine proved this when they found you can take the motor and transmission out of a Z06 corvette and bolt it into a pontiac solstice with no cutting or welding. Including publishing every part number from GMPP needed for the conversion. What they didn't say was how you would change the plugs and wires after bolting it in there.
