Sandy's air helmet is a helmet worn by Sandy Cheeks that allows her to breathe underwater. However, she does not wear it in her treedome, as it is already an air-filled location of Bikini Bottom. It first appears in the episode "Tea at the Treedome."
Description[]
It is an air helmet with a deep pink and golden 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 does not require such equipment.
