Hencho is a Trøg working for Alva Gunderson
He is first seen in Trøgtown in You're the Bean when Dagmar has Bean, Elfo and Luci locked up in the dungeons of Trøgtown. He lets Trixy into the cell to bring Elfo a cake, and Bean seizes this opportunity to capture Hencho through the bars of their cell, after which Elfo and Luci knock him out and take the keys of the door from him.
In "Spy Vs. Spy Vs. Spy", Hencho is seen participating in the fight between the Elves and Trøgs.
His alliances with Alva Gunderson are revealed at the end of the episode "Electric Ladyland", when Alva prepares to go on a trip to Dreamland and asks Hencho to come along with him.
The trip, as it turns out, is meant to bring a rocket to Dreamland with which Alva wants to abduct Bean to the moon, but he needs the Trøg's Sacred Goo to make it work. Hencho is among the Trøgs tht help Alva prepare his rocket, but then abduct him on orders of the Arch-Druidess and stuff him in the rocket before it launches off to the moon with Alva, the Arch-Druidess and all Trøgs on board.
