Maybe there's an ancient magic that connects Harry to a particular group of animals. He has to go on a quest to save them, and during this journey, he and the animals share a series of magical experiences. In the end, a new form of life is created as a result of their combined efforts and the unique bond they've formed, which is like a 'baby' in a very magical context. This plotline would focus on friendship, magic, and the protection of the magical world.

Another plotline could revolve around them working together to save a comrade. They have to combine their skills, with Ichigo's brute strength and Unohona's healing abilities.
