Puffy in the world of Spyfish vs Spyfish.

tshirt-35 (black) front
(#35 -- image is on a black T-shirt)
tshirt-36 (white) front
(#36 -- image is on a white T-shirt)

We could not decide who should live, so there are two versions of this shirt. Shirt #35 is a Black T-shirt where the Black Spyfish wins; Shirt #36 is a White T-shirt where the White Spyfish wins. When purchasing, choose carefully based on the outside border of the image (or, the colour of the spy who lives). Unfortunately this creates a dilemma if you would prefer to wear a black shirt but have the White Spyfish (obviously representing yourself) live. But then, isn't everything a dilemma these days?

Alternatively, you can get both shirts, and when choosing to wear it decide what matters more: the shirt colour, the Spyfish colour, or which one is currently washed. A daily dilemma.
