Written by Daniel Dominguez and Josh Androsky (Food Con Castaways) / Clare OKane (Snail Mail)
Storyboard by Chris Allison and Ryan Kramer (Food Con Castaways) / Chong Lee (Snail Mail)
Animation Directors: Alan Smart (Food Con Castaways) / Tom Yasumi (Snail Mail)
Food Con Castaways contains examples of:
- All Animals Are Dogs: For some reason, there's a snail that howls like a wolf, rather than meowing like a cat.
- Call-Back: A subtle one; when Mr Krabs yells at SpongeBob, Patrick, and Squidward to pipe down he is drawn like Moar Krabs.
- Denser and Wackier: Thanks to the fact that its boarded by two Uncle Grandpa writers and boarders, the episode has a more surreal tone to it.
- Off-Model: Quite a lot of them in this episode, as this is drawn by two freelance boarders who both work on the Toonhole comic and Uncle Grandpa. This results in a lot of weird expressions that you would expect in the grosser season 6 episodes, especially Mr Krabs briefly drawn as Moar Krabs. They would later return to work on Krabby Patty Creature Feature, this time board-driven style.
- Running Gag: Squidward getting covered in ashes
- Suddenly Voiced: In one scene, the Krabby Patty starts talking, and is voiced by Lori Alan.
Snail Mail contains examples of:
- Artifact Title: Despite having "Snail" in the title, Gary only appears in the first half of the episode. Even though Vincent Waller actually made a drawing of Gary delivering mail.
- Get a Hold of Yourself, Man!: Gary to SpongeBob with water in order to get him to stop panicking.
- Imagine Spot: SpongeBob imagines a funeral for his pen pal. The highlights are his pen pal's corpse being inside a giant letter and said letter being put into a mail bin before being buried.
- Recycled Plot: It's basically a rehash of The Sponge Who Could Fly, except that SpongeBob attempts to be a pilot.
