Water helmets are equipment created so that water breathers can come into Sandy's treedome or any place with no water. They first appear in "Tea at the Treedome," coinciding with the first appearance of their creator, Sandy Cheeks.


They are transparent, circle-shaped helmets filled with water, worn by sea creatures so they can be in Sandy's treedome. They also come in various shapes and sizes to comply with certain sea creatures.

Normally the water helmets have one opening in the bottom, but in "Tea at the Treedome," "Chimps Ahoy," "Squidtastic Voyage," "What Ever Happened to SpongeBob?" and "SpongeBob's Road to Christmas," they have two openings, one in the bottom and one at the top.

Role in series

Sandy originally used water helmets for SpongeBob and Patrick when they shriveled up in "Tea at the Treedome." Later, they were used conventionally for any sea creature who came to her treedome.


This list is incomplete, but you can help Encyclopedia SpongeBobia by expanding it.

  • In "House Sittin' for Sandy," SpongeBob is able to go much longer without dehydrating in the treedome than usual until Patrick brings up his lack of a water helmet before putting one on SpongeBob.
