Salmon
What kind of fish jumps from dirt to dirt? A salmon!
かい, けい
さけ, しゃけ
None
You make a drinking game out of watching the salmon going up stream. Every time one jumps onto the dirt, you drink a shot of 酒 (さけ). You realize you're drunk when you ask for more さけ but it comes out as しゃけ.
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.
