A Friendship Saved

When a self-effacing hippopotamus and an inquisitive butterfly meet by chance at the river's edge, friendship is not an option. Or is it?

While exploring the world outside of her forest realm, Sara, a princess of her clan of butterflies, reaches the river home of the hippopotami and there meets Harry and, soon, the two become fast friends. But one day, Sara disappears in a rainstorm leaving Harry fearing she has died. He discovers, instead, that she has been kidnapped and only a fearsome battle among the tree tops of the forest can free his delicate friend.
