Who Shot Elfo? Freckles attempts to trick Bean and Zøg on the hot air balloon and threatens to pop it, only for Zøg to knock him into the ocean. The submarine piloted by Mora sinks but they are saved by Oona, who bonds with Ursula. Per Mop Girl's suggestion, who he has fallen in love with, Elfo uses the crystal ball to travel back in time in order to stop his murder from happening; he aims an arrow at Pendergast who he thinks shot him but misses and accidentally strikes his past self, realizing that he was his own killer. Elfo goes forward and shatters the crystal ball where he, after having a heartfelt moment with Mop Girl, discovers that she has elf ears.
