However, SpongeBob opens the door and water rushes in.

Sandy only has a little bit of air left in her suit, so she goes to her submarine, which has enough air to go to the surface and replenish the air supply for her treedome. Water rushes into the treedome, filling it completely. Patrick simply dismisses her as 'stupid.' SpongeBob tries to help clear the blockage by blowing spicy bubbles onto the airtank, but it melts. Patrick suggests she breathes water like a 'smart person.' Sandy explains that land creatures need air. She tells them she is busy fixing a clog in the airtank. They tell her about their new discovery, with Patrick convinced he is a genius for his new idea, even thinking he is smarter than Sandy. SpongeBob and Patrick go to Sandy's treedome, where she is outside fixing an air tank. Squidward angrily yells at them out the window, but SpongeBob blows a big spicy bubble and it pops next to him, burning him to ashes and crippling him. The beheaded bonsai requests that Squidward avenges it. Just as he is about to clip off a straggler leaf, they scream and he lops off the entire head. Meanwhile, in his house, Squidward is clipping his likeness into a bonsai of himself. They burn each other's eyes repeatedly and the effect goes again. Patrick wonders if hot sauce is bad for their eyes. Then, he blows a spicy bubble into Patrick's eyes, doing the same thing to him. SpongeBob screams as his eyes glow red and disintegrate, then grow back. He dunks his bubble wand into the bottle and blows spicy bubbles into SpongeBob's eyes. Patrick is struck with an idea and takes out a bottle of hot sauce. SpongeBob suggests they 'spice up' their bubble blowing. In the beginning of the episode, SpongeBob and Patrick are blowing bubbles, but soon, they get bored.
