A wild BoinBoin appeared! (Patreon)

You where travelling around to catch some new Pokemon for you collection when suddenly heard a strange sound from the near bushes. You approached them carefully when you noticed the Bush is still shaking a little. You wonder which Pokemon it could be when you suddenly heard a cute voice saying "Boin?". You can't believe it. You are about to catch a very rare "BoinBoin". You put your Pokeball away because you know that a wild "BoinBoin" can be only caught by a special technique...by stimulating it's own balloons.
