SpongeBob SquarePants (1999)

S8E28 Bubble Troubles

While experimenting with hot sauce to make bubbles, SpongeBob and Patrick inadvertently ruin Sandy's air supply by igniting a fire, which leads to her Treedome being flooded. Realizing the gravity of the situation, they need to assist her in locating enough oxygen to breathe. Ultimately, SpongeBob ventures to the surface to create a massive air-filled bubble, which he then places inside the Treedome to restore Sandy's air supply.
