Touch the Sky | Side quests South Park: The Fractured But Whole Guide

After you complete The Thin White Line, Father Maxi will call you. He asks you to go to the lake. On the southern shore, you will see a man in a brown coat standing by a bench - talk to him.

The shady character is in fact, SeaMan. You meet him thin one time.

After a short cutscene, you have to complete a minigame, in which you need to press the action button to avoid the obstacles with a flying unicorn. Should your life end for hitting too many obstacles, you can retry this quest with no problem. As a reward for completing this quest, you can take 3 selfies: one with Jesus at the end of the quest, and two later, when you meet Gayfish and Seaman at The Crunchy's Micro Brew. Do not forget, the Hillbillies are going to attack you as usual.
