The Horse Kings

 is the sixteenth episode of "Backyardigans x Frontyardigans" written by Hornean.

King Austin was put under a spell by four evil queens (Sophie, Henwen, Penny, and Tasha) that transformed him into horse. In his journey to find the four good queens (Uniqua, Ramona, Tina, and Kathy) who have the power to break evil spells, he met eight other kings who have also been cursed by the three evil queens. The side effect for the spell is they turn to normal at night and turn back to horses at daytime and when they're horses, they were unable to speak.
