I don't own much in the way of merchandise anymore. A lot of it was either destroyed by mould or thrown out before I moved out for the first time at 18.
My only merchandise now are things I've bought in the past two years: which consist of 8" plushes of Eevee and Alolan Vulpix and a Build-a-Bear Eevee from a friend. Oh, plus an issue of Pok?mon World from 2004 in which one of my letters was printed.
A Piplup plushie, Torchic plushie, Treecko plushie, Mewtwo plushie, Pikachu plushie, Plusle plushie, Jigglypuff plushie, Tyrunt plushie, Amaura plushie, Pancham plushie, Bunnelby plushie, and an Alolan Vulpix plushie. I’m sure there’s others I’m forgetting as well.
I also have a Pikachu amiibo, a lot of guidebooks for the games, and other cool Pokemon merchandise as well. I keep everything organized on my dresser shelves and stuff in my room at my mom’s, so it looks like an actual Gamefreak room.
Yeah... I started Pokemon with Diamond and I’m kind of obsessed with it nowadays... lol
I have a few favorites so it's a bit difficult to pick just one absolute favorite. But it could definitely be my fluffy plush Eevee that I bought from an online store a while ago since I was specifically looking for an Eevee plush that's decently sized. It was a great purchase since it's so comfy to hug.
I also have a couple of Pokemon T-shirts, a Detective Pikachu one, and one with a pokeball and the text "Pokemon trainer" on it. Those are on my favorites list for sure too since clothes are cool. Speaking of clothes and the like, yet another favorite of mine is my Jigglypuff scarf. I like it so much that I've worn it indoors.
Also, I've posted this picture in another thread before, but there's a picture of the Eevee in the spoiler!
I don't own one at this time, but I kind of want to get one of those big Snorlax bean bags. They seem neat. Don't really like the price though, which is why I've never gotten around to getting one.
As for things I do own, there are a few things I suppose. I never got into plushes for Pok?mon, so nothing like that. I have some Pok? Balls with a little plastic bit you can clamp to your clothes and that you can take apart and put back together, they came with little toys inside. I found them when I was a kid back in the Generation I era when the boom was still going on. It was kind of neat as a kid to clamp them on like they did in the show and make it seem like you had your team with you.
They also used to sell bouncy balls with certain Pok?mon inside. I have one with Mew and I always had a fondness for it since I've always liked Mew and because, as bad as the first movie is when looking back on it now (at least the dub, haven't seen the sub), it was reminiscent of seeing Mew flying around in that little bubble in the movie.
There might be something else, but I can't think of it at this time if there is. I've never really been one for anything that isn't the main series for Pok?mon, be it the TCG, side games like Mystery Dungeon, or merchandise.
I collected a lot of plushies over the years and so far my favorite one would be my old Eevee doll. I was naughty when I was a kid and I cut her fur off, but other than that, she's still in great shape and still my favorite. I also really love my Pokemon t-shirt with the Alolan theme.
It used to be my Pokemon cards, but I don't have them anymore. I do still have some plushies I keep stored to prevent them from getting dirty, but I haven't bought any recently. I have one strategy guide of Heart Gold of Soul silver and the rest of the guides or mags I own digitally, it lasts longer that way and doesn't get any damage from reading or moldy from storage.
