It’s a hot, hot, hot day in Danville, and Phineas and Ferb know what they’re gonna do: build a beach in their backyard! As they create a magnificent coast, filled with hula-dancers, surfing competitions and impromptu musical numbers, Candace once again tries to inform her mom, but finds herself enjoying the beach despite herself. But how long can their fun last when the evil Doctor Doofensmirtz has set out to steal every single lawn gnome in the Tri-State Area?
Tropes:
- Artistic License – Physics: Stanky Dog says that Phineas's surfing has made one of the judges question Albert Einstein's theory of relativity. However, the formula on the placard is a crossed out E=mc^2, which is not the relativity formula, but actually the mass-energy conversion formula. A common misconception among those only slightly familiar with science.
- Bait-and-Switch: During the song; Buford tries to bully an unnamed, glasses wearing kid who was being buried in the sand by two girls, by kicking some sand in the kid's face. Enraged, the kid stands up revealing an incredibly thick, and muscular body much larger than Buford's resulting in Buford getting frightened and running off. After he disappears, the sand falls off revealing the kid's actual scrawny build.
- Beach Episode: Phineas and Ferb turn their backyard into a beach.
