8-Bit Octopus Graffiti
In the map, Urchin Underpass, you can spot 8-bit mosaic art depicting both Bloopers from Mario and Octoroks from Zelda on opposite sides. Given the rivalry between squids and octopi in the Splatoon game, it's no surprise other creatures from Nintendo have taken sides as well.
Hidden Controllers
While you are positioned outside the Battle Dojo in Inkopolis, peek into the window. To the left, you should spy a white Wii U gamepad and a gray pro controller, while to the right there is a black one.
Various General Tips
Always be putting ink on the ground. Don't worry too much about shooting other players right out of the gate. Remember that the victory conditions are entirely about the amount of your team's ink on the map.
Only shoot ink on walls when you want to travel to a higher spot. It does not count towards the final percentage at the end of a match.
Remember you can test weapons before you purchase them. It'll help you save some coins and help your team if you happen to perform poorly with a charger in the test level. Better to find that out before an actual match.
Ranked matches are unlocked once you reach level 10.
Play through the single-player mode to unlock blueprints for new guns in multiplayer.
If you see a cool piece of equipment on a character in the plaza, click on them and order their gear. It costs a bit more, but what's a few extra coins in the name of fashion?
Try to purchase gear with more ability slots.
The shopkeepers change their inventory every day, so be sure to check back to see what new items have arrived in the stores.
When you get your special, get to a safe spot and use it. If you get splatted before you use it, you have to charge up the meter all over again.
You can spawn on a teammate at any time by clicking their icon on the gamepad. Just be sure they're in a safe spot so you don't get splatted immediately.
Remember to go back to the plaza every now and then to check out the Miiverse posts. You're bound to see some fantastic artwork (and way too many Spongebob Squarepants posts).
