For the turtle some background and more characters from the cartoon(if it is a cartoon of some sort)

For the other one a long sleeve shirt is what I would add.

You’re wearing the same shirt in both pics. Did you have these done at the same time? What was that like?

“Yeah, Bob, I’d like a proclamation of my faith on my left arm… And a cute baby sea turtle on my right. No… Cuter… Cuter… DAMMIT, BOB, it’s supposed to be cute! … That’s more like it.”

Is the turtle from Finding Nemo? Obvious choices then are more Nemo/Pixar stuff.
