Super Edition: Firestar's Quest
In Firestar's Quest, he starts have the same dreams as Firestar. He remembers that Firestar, then Rusty, had strange dreams when he left to join the "ruffians" of the forest. He was found by a patrol, and luckily Firestar was nearby. He heard the fight, and stopped them from chasing him off. He later finds out that his Twolegnest is built on the site of the old SkyClan camp. While they are talking at his Twoleg nest, he introduces Firestar to Hattie, who moved into Firestar's old Twoleg nest. He lets Firestar spend the night in his yard, hoping to find some answers.
