Separated from her Rider during battle, Horse wakes up in a colorful world filled with strange beasts.
The herd sets out to find the way home; Wammawink encourages them to be careful and take it slow, but fearless Horse charges ahead.
Horse meets Waterbaby, a shaman, and learns about the key -- a mysterious object that could reunite her with Rider.
Searching for the next piece of the key, Horse leads the herd into a mysterious forest to see the tree shamans; they grant wishes, but there's a catch.
The friends seek shelter in a cave during a storm, but they're not alone; while looking for an exit, they discover strange paintings on the walls.
The group follows the Rainbow Road into a deep, dark hole, where a Moletaur locks them in jail and informs them they'll face a judge.
