Sandy's air helmet is a helmet worn by Sandy Cheeks so that she can breathe underwater. However, she does not wear it in her treedome, as it is already an air-filled/water-free location of Bikini Bottom. It first appears in the episode "Tea at the Treedome."


It is an air helmet with a pink and yellow flower on the upper-left side.

Role in series

Sandy is required to wear this air helmet when outside of her treedome to make it so that she won't die from a lack of oxygen, as seen in "Pressure" where her lungs deflate after being challenged by the sea creatures to breathe without her helmet and she quickly puts a pickle jar over her head to recover.

However, when in her treedome, she removes the helmet, as well as her astronaut suit and boots, since her house is an air-polluted area of the ocean that doesn't require such equipment.
