- In "City of Thieves," Finn was originally going to proclaim he and Jake were virgins, which was edited by network standards to "virgin islands."
- In "Wizard," Finn and the Old Wizards were originally going to have their nudity covered with a beaver, but network standards changed it to a log.
- In "Tree Trunks," network standards added in a scene of Tree Trunks walking in front of a background said to be the Crystal Gem Apple, because just having her explode was considered "too dark."
- In "The Enchiridion!," the original title card had Finn stabbing Jake with a dagger, but the network standards changed it to Finn holding a french loaf, due to the scene being too scary.
- Cartoon Network featured Adventure Time on FusionFall. One of the quests is "Snail Quest," where the player searches for the hidden waving Snail.
- The previous CN Studios logo starts off with Finn and Jake. Finn touches Jake and then Jake grows larger and fills up the logo, ending the sequence.
