Rocket's Island

With the annual village show just around the corner, Rocket and Alli are dismayed to learn that their family is fostering two mysterious newcomers.

Rocket confronts Casey and Lena before they can drive off on Peter's tractor. Meanwhile, Alli is crushed when Sarah doesn't make it to the village show to see her compete.

With just hours left in the doomsday prophecy, Alli and Rocket come closer to learning the truth about Casey and Lena.

The Boulsworths are expecting new foster child Brandon Kelleher, but he runs away before arriving at the Knot. Later, an old phone booth rings in the village and a mysterious voice tells Rocket where Brandon has gone.

When a mythical Tancath is sighted in the woods, Rocket is determined to see the creature for himself. There he discovers Jade, a previous foster sibling, and learns that she has hitch-hiked back to the island.

When eccentric old Mary Mac's house is destroyed, she comes to stay at the Knot. Jade soon discovers that she is the ancient Queen of the Fairies, which could explain why the children's possessions have been disappearing.
