"A scooter!" you announce. You are announcing this because you decided this is what you would create.
ぞう
つく
None
But, a scooter has been created before. What is different about yours? The scooter you will create is specifically designed to keep zombies (ぞう) busy.
An update is needed before you can continue but you have more than one WaniKani tab open.
Finish up what ever you are doing on the other tab(s), then close them to continue.
The update will complete automatically once the other tab(s) are closed.
