The very same shirt ^_^
My current collection of clothes with Ninja squid:
Zekko hoodie : Ninja squid + 3x speed up
White anchor tee : Ninja squid + 2x ink resistance + refill (maybe keep it like that)
Shirt & tie : Ninja squid + 2x main saver (aim for 3x)
Camo zip hoodie : Ninja squid + 2x sub saver (aim for 3x)
Negative longcuff sweater : Ninja squid + 2x refill (aim for 3x)
Matcha down jacket : Ninja squid + 2x refill (will scrub)
Prune parashooter : Ninja squid, working on it (want 3x swim speed up)
I also have cycle king jersey, shrimp-pink polo and b-ball jersey with Ninja squid on them, but I'm not sure I'll find many more ideas for builds
Yes, that's my feeling... Aiming for main saver, ink refill and swim speed (especially with Ninja)
