This is the mascot for Sprigatito from the "Transform! Ditto" series.
 
This is the challenge story of Ditto, who is not good at the "Transform" move.
Ditto tries its best to transform into other Pokémon, but its face remains that of Ditto, and this has been turned into a plush toy!

You might be able to understand how Ditto feels when it's not good at "Transform"!
