There is something about Ditto that will forever endear the Pokemon to me. Something about the permanent derp-face, the unique ability to transform into any Pokemon, and the ability to mate tirelessly, producing eggs en masse until you get the perfect IV distribution all comes together for a Pokemon who just desperately wants to be loved.
So it makes sense, then, for Ditto to try and work it's way into all things Pokemon. The officials in charge of this kind of thing are well aware of people and their love for Ditto, and so these upcoming Pokemon plushes are a salute to that love.
It's not the first time we've seen Pokemon plushes get all ditto-ed up. A month or so ago, The official Pokemon Center started retailing these ditto-fied starter pokemon (and Clefairy).
Who could resist an adorable Ditto trying it's hardest to be loved?
