Pokémon The Series: Sun & Moon

Why Not Give Me a Z-Ring Sometime? (21x29)

:

When Mareanie shows it can use Knock Off, a Dark-type move, Team Rocket realizes that now they'll be able to do a Dark-type Z-move with their Darkinium Z crystal ... if they only had a Z-ring! Team Rocket boss Giovanni tells them to go to Ula'ula Island and see Island Kahuna Nanu, an old acquaintance of his, but when they get there (having left behind talking dummies of themselves to fool Bewear) they're told by a grumpy old man that Nanu has gone on a training pilgrimage and won't be back for a long time! When Jessie, in her anger, smashes an old tombstone, she releases a giant Gengar who steals their Darkinium-Z crystal. Later at the local library, a girl named Acerola, after reading a scary story about a wicked Pokémon to two children, is kidnapped by Gengar, who flies off with her stealing everything. Her Mimikyu flies after them and tries to rescue Acerola, but fails. Gengar offers all of the stolen items to Acerola as gifts, but she refuses to accept them, as they are stolen, and Gengar in a temper tries to possess Acerola, but Team Rocket has been following and Jessie's Mimikyu attacks Gengar (with James secretly retrieving their Darkinium-Z crystal). Team Rocket teases Gengar into losing, then runs off with Gengar in pursuit; when it catches up to them, the battle gets very confusing and is only halted when the grumpy old man and Acerola appear. The old man (who is actually Island Kahuna Nanu) gives James a Z-ring and he uses the Z-move Black Hole Eclipse with Mareanie to defeat Gengar. As a reward for helping her, Acerola (Nanu's niece) gives Jessie a Mimikyu Z-crystal.
