The Ugly Barnacle is a very-short story Patrick told SpongeBob in Something Smells. It was meant to boost SpongeBob's self-esteem, but it only made him feel worse. Because of this, Patrick insisted they scream to get rid of his depression instead.
"It's called the Ugly Barnacle. Once there was an ugly barnacle. He was so ugly that everyone died! The End."
- It has spawned popularity on YouTube.
- It is an obvious parody of The Ugly Duckling.
- Ugly Barnacle videos seem to have the former Nicktoons Network logo.
