S01E21 — No Free Lunch

While on a field trip to a cave in Japan, Zoe is asked to sit next to a new student named Amy when she's on the bus, and just make her feel welcome. But as some girls in the row behind them start talking about lizards, Amy starts to feel a little sad, and she shows Zoe the picture of her former pet iguana, Hana and how they had to leave her behind when her family moved in. But she wanders away from the group when she finds a lizard, and also finds an Euoplocephalus and makes friends with him.
