Kaksu

Behavior

Appears as Bug-battling Kaksu before interacting. Kaksu appears in the Bug battling children group both day and night in The Cistern.

Kaksu is involved in the Bug catching quest. If you have a Lanternmoth, you can battle Kaksu's tombac snail by pressing the exchange icon.

Haha! Take that!

If you beat them at bug battling:

Haha! That moth of yours sure was quick! Way too quick for my tombac snail!
