The Bubblestand is a stand that SpongeBob built. People could blow bubbles for 25 cents. It only appears in the episode "Bubblestand."
The Bubblestand is made out of green wood with a sign that displays in red font: Bubbles 25¢. There are signs under the Bubblestand that display Lessons 25¢. SpongeBob also offers lessons for beginners for only 25 cents. SpongeBob then does a technique for blowing bubbles. Squidward tried to learn without following the technique, although he was unsuccessful until he followed it. Patrick also got some lessons and did well.
SpongeBob (Teacher): Makes a duck and ducklings, elephant, ice cubes, caterpillar, boat, and butterfly bubbles.
Patrick (Student): Makes nothing because he struggles. He does however help SpongeBob teach Squidward the bubble-making manoeuvre.
Squidward (Student): Only flat bubbles that makes raspberry sounds when pops, and finally, a BIG bubble that swallows his house, and a loud explosion is heard when it pops.
