Once you are in Brical de Mar, you will have access to several new side quests. These include the Missing Kids quest, in which you need to find two missing children.
To complete this quest, you need a surfboard, which you will get during the main storyline. On the first island, you’ll be told to get to the Dojo in Arissol.
Once you are in the right place, you will know that Sofia, the leader of the Dojo, went north to Fort. You must go after her and rescue her. Once you do that, the dojo will open in Arrisola. Finish the dojo by defeating Sofia, and she will reward you with a surfboard.
How do we start the quest?
Go to the Academy building and go upstairs. Go into the office on the left and talk to the Academy Director. Ask if she has anything you can help with. She’ll ask you to find two kids in Brikala, Yusuf and Roger.
Where can I find Yusuf and Roger?
Once you have a surfboard (guide above), head west to Brical de Mar and go to Lake Indigo. Yusuf and Roger are in the southwest of the lake. Talk to them and then go back to the director.
As a reward, you will receive the Bait, with which you can catch the Temples, as well as escape from the wild TemTem.
