For my pet Johannes Krauser II

For those of you unfamiliar with Detroit Metal City, it's a fan pet based off a character from a series/live action film where a farm boy who dreamed of making trendy pop music in Tokyo wound up becoming the front man for a hardcore death metal band after graduating from college. He struggles throughout the series/movie making a breakthrough on the pop music he really dreamed of performing, while the death metal band and his alter ego (the pet's namesake) flourishes and gains popularity, much to his chagrin.

With that tidbit of info out of the way, what other items would you suggest for Johannes aside from what is already in his chest?
