If you haven’t jumped in yet, let me assure you that all the Adventure Time comics are really good.
Adventure Time - “BMO’s Pregnant Song” (Adventure Time, s05e19; “James Baxter the Horse”; 2013)
Oh! Oh, BMO!
How’d you get so pregnant?
“Who’s the mother? Oh, who’s the father?”
Shh! I’ll tell you—if you keep it a secret.
"We will! We will! We willllll!"
Last night, an electric presence came into my room and said,
“BMO, I need-a your perfect body to host the human incarnation of a baaaaay-beee!”
Snail - The Adventure Time Wiki. Mathematical!
The Snail is a character that has hidden in every episode of Adventure Time to date (excluding the Animated Short), usually seen waving at the screen. His cameos are a running gag.
He’s also hiding in all the comics. One of my favorite little easter eggs out there.
Definitely our household’s contemporary Goldbug.
