Pokémon The Series: Sun & Moon

The Long Vault Home! (21x41)

:

Viren turns up again, this time overseeing the construction of a resort known as Viren Tower. A new rock/steel-type Ultra Beast called Stakataka turns up first at the Pokémon school (where it's mistaken for a new type of vaulting box), and catching it, even though it doesn't move, turns out to be harder than expected and they are forced to give up for the day. During the night, it moves itself to Viren's building site. When Viren, mistaking it for a statue stand, glues a golden statue of himself onto it, it goes berserk and the Ultra Guardians are once again called into action! Another unorthodox "Ash strategy" enables him to calm down and capture Stakataka, who is later released into an Ultra wormhole back to its home.
