Tree Trunks' Alien Husband makes his first and only appearance in "High Strangeness". It is shown that he occasionally visits Tree Trunks. When her husband, Mr. Pig awakens from a visit, she refers to him as a "beau" at first and tells him not to feel threaten as Mr. Pig has a special place in her heart. Thinking she's either dreaming or joking, he shrugs it off and goes back to sleep. It is hinted that the unnamed gray alien will randomly transport her to his ship and that they have several hybrid children together. However, Tree Trunks is quickly returned home. It is never stated how long she has known her alien husband and if this was before, after, or in between her previous marriages.

Later in the episode, Princess Bubblegum sets off a rocket that resembles her countenance into the sky. Seconds, after it flies into space, Tree Trunks is abducted by aliens, who point out the rocket that has crashed into their realm. The rocket head opens to let out streams of candy matter, which begin to invade and attach themselves to the aliens' bodies. Tree Trunks is transported back to Ooo, and she immediately berates Princess Bubblegum for hurting the aliens. Princess Bubblegum is surprised that Tree Trunks knows the rocket went into space but insists she does not know what she's talking about. Later, Tree Trunks and PB are both transported to the alien world.

Princess Bubblegum apologizes as she intended to seed new Candy Kingdoms on uninhabited planets in case something catastrophic were to happen to Ooo. The Alien husband then agrees to fly Princess Bubblegum's probes to his abandoned home planet so they can start their new Candy Kingdom, but the galaxy is so far away, he will not be able to see Tree Trunks again for another 40 years. To which she accepts but pleads him to tend to their children,

In the series finale "Come Along With Me" final montage, Tree Trunks is seen offering an apple pie in a crop circle, presumably to him and their children.

In "Together Again", he appears with Tree Trunks, Mr. Pig, Randy, Danny and other ex-husbands, enjoying the 30th Dead World. He later falls into the 1st Dead World, but is freed at the end of the episode.

The Alien Husband is a slim alien with gray skin and big greenish-black eyes.


  • Princess Zip, a character in the far future, highly resembles him, suggesting his species will eventually settle on Earth.
  • Given how in most sci-fi fiction grays are known to "create" hybrid children through experimentation, thats most likely how they have their hybrid children.
  • Its somewhat unknown how/or where Mr. Pig stands with the relationship. Its clear Tree Trunks hints she wants polygamous relationship with both. Though Mr. Pig never seen giving her a answer or response, due to shock. But an answer is never really shown and Mr. Pig has been known to be uneasy about men even making comments about her or do things even fakely intimate (such as a kissing scene when she was in a play), so its somewhat unlikely he'd be okay with Tree Trunks plan. And was once afraid she'd leave him for one of her exes. But given they are together till the very end of the series Mr. Pig either accepted Tree Trunks life style or may go along since her "husband" would not return for another 40 years; which meant he could somewhat ignore sharing her with someone else.
