How to get cool badges at Nintendo Badge Arcade

I would not say Nintendo is trying to snag our money and empty our wallets. Yes, it's annoying that the bunny pesters us with requests to switch to paid play but it's like Pokémon Shuffle and Rumble World. Money is not needed to enjoy them. And if you have a dollar just laying around in your eShop balance and nothing to spend it on, then that's your choice. It's not like you're not being forced to pay. Or even worst, having to pay for the rest of your life. We should be glad we're getting free play opportunities. And the badges are just little decorations to put on your home menu. They're not that big of a deal.
