The fins in "Katie Island Adventure" are an important prop in the game. It allows you to swim in the water and explore new areas. When creating fins, you need to find them there after unlocking the ghost swamp. Kairobe, the frog, crossed the bridge and climbed a purple hill with wooden boards.
How to make fins on Katie Island Adventure
After unlocking the Ghost Swamp, you can find the Kerobi frog there. After crossing the bridge, climb up the purple hill with wooden boards. If you keep going east, you will eventually find him.
Make sure you have activated the Find Flippers task, which can be activated by approaching any water.
Once you interact with Kelobie and upgrade to friendship level 1, he will give you a plan for making fins. On the workbench, use 1 fin and 1 tie tape to make fins.
Kyrobi will give you fins after you become friends with him, so this part of the material has been solved. However, finding straps can be a bit difficult because you can’t find them in an open world and aren’t a quest reward.
Currently, the only source of tie-in bringing in the game is a specific box. Enter the north of the ghost swamp. If you walk to the wood structure above the water, you will find it there.
