This page is dedicated to the Passing the Swim Test level found in Beach Bowl Galaxy.
Grab the Golden Shell
This is one of the more straightforward levels in this game. A large penguin on the wooden bridge. He will tell you to bring him the golden shell as a part of the swimming test.
Dive into the water and find the group of penguins swimming around. The one at the front of the group will be carrying a golden shell. To grab the shell, press Y. Then, take it straight back up to the large penguin to earn your Power Star!
Tip: Spin by pressing Y or shaking the Right Joy-con to get a small boost in the water.
