When the main Yo-kai Watch toy became a phenomenon in Japan, it was inevitable that The Pokémon Company would fancy a bit of the action. Z-Ring toys for Pokémon Sun and Moon effectively do just that, as large plastic wearables that light up and interact with the game. Beyond the core toy there are plenty of 'Z-Crystals' to collect, so it could be a money-spinner if it takes off; early pre-orders on Amazon in the West were positive.

A new official trailer in Japan makes a pitch for these toys, showing two young Trainers getting transported into the Pokémon world - in reality they light up a bit and trigger Z-Moves, but it's effective advertising.

Do you think these toys could be a success, or are they a gimmick that'll struggle to take off? Sound off in the comments.
