Really Small Problems

When Hexside is closed because of a pixie infestation, Eda receives an invitation to a pop-up carnival. While there the gang runs into Tibbles, who now owns a miniature circus called the "Tent of Tiny Terrors". King and Luz run into Willow and Gus, who were also invited to the carnival by Tibbles. Jealous and feeling left out by the other three, King is tricked by Tibbles into shrinking Willow and Gus with a potion. Luz finds out about it and confronts King, but they end up shrinking themselves after fighting over the potion. King and the children are captured by Tibbles and put in his tent where they are chased by his miniature beasts. Realizing that all of this is his fault, King tricks Tibbles into restoring everyone to normal size. Eda drives Tibbles away and Luz, King, Willow, and Gus all have fun together at the carnival for a few more hours. (Source: Wikipedia)
