Ash, Brock and Misty head towards Mt Moon so they can get to Cerulean City, but they encounter a man being attacked by Zubat's. He introduces himself as Seymour and says that the Pokemon in the mountain are acting strangley due to lights inside the cave. The group then bump into Team Rocket and Butterfree and Brock's new Zubat battle them. Then they chase after a Clefairy and settle down before they find the Clefairy cave and their Moon Stone. Team Rocket end up stealing it and going down the mountain btu Onix stops them. Some of the Clefairy's evolve to Clefables and blast Team Rocket off. Ash's group leaves Seymour and reach a sign in which Gary has written stuff about Ash on.
This was an alright episode. I thought that Seymour's oddness was rather funny, and I liked the storyline of the Clefairy's and the Moon Stone. I liekd the part when Team Rocket went down the mountain with the stone before being hit by Onix. A lot of different Pokemon were seen which was good, and it was nice that someone other than Ash caught a Pokemon. Some of the things were a bit silly, with the ideas about Pokemon coming from space and that the Clefairy's thought the moon stone was their good, but it is an animation after all. Overall, it was an alright episode with a few improvements needed.
