Gill appears! - S1.E11

Al and the gang are slowly approaching Victoria island by ship, when they are suddenly attacked by a human. They make a hurried landing, but Anji and Nina split up right away, and Barrow and Gallus are fighting on who the leader is. Al gets separated when a little monster asks for his help to save a friend. He meets the human from earlier there, who calls himself Gill the Monster Slayer. He asks the little monster about the World Tree seeds, to which the little monster says that he saw a Yeti. Gills asks the little monster to take him to the Yeti, but not finding it, tried to kill the little monsters. Al tries to save them, but gets trapped by Gill's move and is finally saved by Yeti. Barrow, Gallus and Nina arrive to help him and find that the Yeti has already rescued and healed him. Gill finds them and refuses to join the gang when Al invites him. They finally figure out that the Yeti has already planted the seed, but it turns out to be a completely different plant. Finally, we see the little monsters calling the gang as the Legendary Heroes.
