Like there is a little change to get a shiny pokemon (i think its
1/69000) there should be a little chance of getting a shiny plushie
when it's sent to you,
another suggestion is that in Pokeradar there is a shiny plushie
hunt button
No Support. The Shiny Plushie chance was already suggested before
and a Shiny Plushie radar makes no sense because they are gifted to
you and not hatched.
No support since things similar have been suggested before and
shiny Plushies will be added later. One is already in the store now
and it is 200 DP (a lot) so I think it might be better to just save
200 DP and buy a shiny instead of making a way to just randomly get
one for maybe cheaper or maybe more expensive if the odds are good
or bad.
