These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: Pokémon: Jirachi: Wishmaker
Hilarious in Hindsight: Take a good, long look at the fake Groudon from this movie. Flash forward to 2014 and the Gen IIIremakes, Omega Ruby/Alpha Sapphire, introduce Primal Reversion, a transformation for the mascot Legendaries similar in function to Mega Evolution. Three guesses what Primal Groudon greatly resembles.
I don't think the Pokémon universe is so cheesy that it would actually make a wishing trinket come true. The real point on that thing was as a clock of sorts, to remind the viewer what night it was. And it worked quite well.
