If you're looking for episodes where Shippo is particularly prominent or has a big role, you might want to look for episodes where:
* He's the main focus: There are episodes where Shippo is the one who needs rescuing, or he's the key to solving a mystery.
* He has a lot of screen time: Some episodes center on Shippo's training, his interactions with animals, or his mischievous side.
* He gets to showcase his powers: Shippo's fox demon powers are occasionally highlighted in particular episodes.
Unfortunately, there's no easy list of episodes where Shippo has a larger role than others. He's an integral part of the Inuyasha group, so he appears in almost all of the 167 episodes.
