 * At the magic fountain, Ava's grave splits open and Ava rises as the blue Friendship Heart is fused back together. Thanks to William, Danny, Pally and Magic showing thoughtfulness, selflessness, kindness and protection respectively, the four elements comprised the magic of friendship that was garnered through the then-broken blue Friendship Heart. This magic coupled with Ava's strength in magic and royalty, allowed her to be resurrected. Ava and the four dogs rise up in a large glowing ball of magic, and fire a beam at the Petbuster that kills him. Ava spreads out the magic across Pocket Kingdom, creating the friendship blessing, and sends off Pally to Robert.

Three weeks later

 * A tribe of hyenas called the Zecorans, based on a remote island, repel the blessing, catching the attention of Ava, who sends William and Danny to investigate.

 * The royal guards have a meeting, and Ava tells them that by the sounds of it, the Zecorans are following in the footsteps of ancient dark magic practioners, whom her ancestors defeated in a war.
 * A funeral is held for Drew.
 * Ava sends the winged guards and Pocket Kingdom military to the island to arrest Zeco and neutralise the threat, but the island has already been abandoned, and the Zecorans use dark magic to unleash a thunder storm and aggresively shoot lightning across the land, one bolt striking Ava. Magic, William and Ava use the three friendship hearts to heal her, and Ava manages to use her magic to hold back the storm.

Next day
