The construction of the Treedome is Sandy's primary adaptation to living underwater, providing a breathable atmosphere and terrestrial environment for her to thrive.

Early episodes highlight the challenges Sandy faces interacting with underwater creatures, particularly when they enter the Treedome and experience the unfamiliar terrestrial environment. She often acts as a guide, explaining the differences between land and sea.

Sandy develops various underwater gear, such as water helmets, to allow her friends to visit her in the Treedome and to explore the underwater world with her. These inventions facilitate her integration into the Bikini Bottom community.

Sandy constantly strives to maintain a balanced lifestyle, dividing her time between her Texan identity, her scientific pursuits, and her friendships in Bikini Bottom. This requires ongoing adaptation and compromise.
