However, he is sent to the wrong family, forcing him to return to the Island of the Ilús, a mythical place where all animals live before they are born. Unwilling to accept this, Pocó wants to meet his real family, even if it means discovering a secret passage at all costs, a passage known only to Rinco, the leader of the rejected animals' clan. His best friend Oli helps him on this journey, even though Pocó has no idea that she is a spy for Gakra, an evil reptile who intends to invade the island and shake up the entire animal kingdom.
