Trivia

 * Pendleton Ward has confirmed that Schwabble is based on his friend Marie's dog Schwabble. Schwabl is a white male poodle that has recently passed away and is seen on the show as Marceline's zombie dog that roams around her house.
 * In "Marceline's Closet," Jake uses a dog door to enter into Marceline's house. It can be assumed this was built for Schwabble.
