Beach Episode/Western Animation

Examples of Beach Episodes in Western Animation include:

WITCH has one in the second season episode "I is for Illusion" where the girls go to the beach to relax on summer vacation, though unlike other examples it's anything but Filler as The Chessmaster Nerissa attempted to sow seeds of discontent amongst the girls, and very nearly managed to steal Will's Heart of Kandrakar. In the very next episode, "J is for Jewel," Irma is still at the beach with her family as they decided to stay a few extra days while the other girls leave, which leads to a big problem when she's needed to help fight and is separated from the rest of the girls.

- One Season 3 episode is entitled "The Beach" If you hadn't already guessed from the title and the page image here, yes, it is indeed a Beach Episode, featuring Ozai's Angels (+ Zuko) in swimsuits. The preview images, particularly Ty Lee's, erupted into quite a scandal in the fandom. Unusual for a Beach Episode in that it climaxed in a very dramatic scene that not only revealed the Freudian Excuses for Mai, Ty Lee and Azula, but also an important part of Zuko's character development.
- The Grand Finale also had a brief scene at a beach. Sokka tries to get everyone to chill out, only to be derailed by Zuko's attitude... and fireballs.
Ben 10 does this in both series. In the first, they're children, and it's summer vacation, so there's nothing surprising or scandalous about them going to the beach (and a water park). In Alien Force, they're teenagers, and it's apparently later in the year (as everyone's normal day clothes have long sleeves, a jacket, etc), but they still find a reason to go to a lake and splash around for five minutes. The boys wear typical swimtrunks, but Gwen's swimsuit has gone from a high-necked one piece to a very revealing white bikini in the style of Ty Lee's up there...

- There's an episode about surfing, but the surfing was left for the near end, since they were looking for the perfect waves. Bonus points go for Austin and his "Mystery Lifeguard" song.
- "Legend of the Volcano Sisters" was also a Beach Episode.
Several episodes involving Shego in Kim Possible, since she does enjoy sunbathing during her vacations. Come to think of it, she doesn't even need a beach....
Although several Chip 'n Dale Rescue Rangers episodes involve beaches, the one true beach episode is "Shell Shocked" because Gadget is wearing a swimsuit. A one-piece swimsuit with attached skirt, but a swimsuit.
The Futurama episode "The Deep South" is primarily a beach episode, and the movie Benders Big Score features a prominent scene with everyone at a nude beach (also highlighted in the DVD packaging).
Even Hey Arnold! has one ("Summer Love", a.k.a. Beach Story). It helped to develop Arnold and Helga's UST and throw some fanservice by the character-of-the-week, appropriately named Summer.
Winx Club features the girls in their swimsuits by a lake. There's also a 3-D music video called "Mambochiwambo" that filled the role, more or less.
Phineas and Ferb has a few. In one episode they make a beach, and on another occasion they go to a genuine one to find a lost goldfish, and then in a later episode they return to search for Atlantis.
An episode of Rugrats when the gang goes to the beach where Tommy and Chuckie attempt to release a bowl of brine shrimp back into the sea.
When the heroes of Dinosaucers are prevented from battling their arch-enemies (the Tyrannos) because of a holiday both factions hold sacred on their homeworld, their human allies decide to take the opportunity to show the dinos how to have fun in the sun. Hilarity ensues when Dinosaucers and Tyrannos end up on the same beach.
SpongeBob SquarePants has some. One centered around SpongeBob ripping his pants, the other being a lifeguard, and in a later episode fighting with Patrick with sand castle mecha.
The Amazing Chan and The Chan Clan episode 3 featured the kids having a relaxing day at the beach, until it was interrupted by a crook framing their Pop for a string of robberies. Luckily, they got to resume their fun once the case was wrapped up.
Jimmy Two-Shoes has "Heat Blanket Jimmy", where Jimmy decides to throw a beach party to beat the heat. Naturally, when Lucius finds out, he tries to ruin it.
The Gravedale High episode "Do The Rad Thing" is to be considered as one. It's about Gill missing school and eventually dropping out to practice for a surfing contest with his human idol, Kahuna Bob. Also, the class spends the night at the beach trying to convince Gill to come back to the school.
Ed, Edd 'n' Eddy: Hot Buttered Eds. Eddy attempts to get his "spot" at the swimming hole back from Kevin, and Edd freaks out lack of sunscreen.
The Pink Panther: "Come On In, The Water's Pink", where the Pink Panther visits Bicep Beach and makes good use on a whole bag of self-inflatable items to upstage the strongest man on the beach.
In The Ant and the Aardvark cartoon, "Dune Bug". While the Ant is trying to have a nice time at the beach, the Aardvark shows up and starts trouble. The Aardvark must try to catch the Ant, while trying to stay away from the lifeguard who thinks he is a dog.
Done in Trollz, with three of them making up the last story arc.
Jimmy Neutron has "Beach Party Mummy" where the gang plays hooky due to a boring lesson on Egypt, deciding to go visit the real deal complete with having a beach party, finding an ancient tomb and giving Libby a permanent make-over, which resembles the Egyptian Queen Howzaboutislapya.
