How to do the Katie Island Adventure Dyeing Upgrade Task
The task itself is relatively simple. You just need to find the cool penguin and Kulomi and complete their own small tasks for them.
Cool Penguin
After talking to the cool penguin, you will learn that the dye you need is in a box next to him, but he wants to put something else in and replace it. So you need to go to Melody and talk to her. She will hand you a table, you can hand it to the cool penguin.
When he gets the table, he will open the box so you can get the dye.
Kuromi
Go to where Kulomy is and talk to her and you will learn that the dye is in a box too.
Return to Sam Penguin
