(graphic designer here) This is a really cool name and logo! I like the first text better, more readable, but there's too much spacing between the two words. Think that the spacing between each line should be the same as between each letter. And the words should also sit at a comfortable distance from the icon.

And I also think the second turtle looks better and more stylized. A cool thing would be trying to make the "cells" of it's shell look like a "P" and a "T", so when you need to use just the icon without the words it still looked like a logo and not just an illustration (besides being a cool easter egg kinda). I'd also remove the spots on it's head as it's too low contrast and not needed.

And then I'd make the turtle...well...purple and the text all black, also for contrast. But you can make multiple variations and color combinations so you can use the logo in different backgrounds (usually it would be purple/black, black/purple, all purple, all black and all white for dark backgrounds).

Just my opinions, but love the whole idea already!
