I only recently became interested in collection Pokémon items again, and I totally blame the Pokémon Time Eevee Collection. I saw photos of the mascot plush going around tumblr and they were some of THE cutest things I had ever seen in my life! After figuring out how to get my hands on my favorites, I was introduced to the world of Pokémon merchandise and have been keeping up with news and occasionally picking up new items ever since. I particularly like small plush and things like keychains/straps and pins, especially ones with particularly unique or adorable designs. I don't collection one Pokémon above all others, but I do admit that Cubone is especially dear to me.
Here's a picture of my small collection. The kuttaris and Halloween pins are from Nintendo World--living in NYC has its conveniences! I'm hoping Nintendo World will stock this year's Halloween items and the other two waves of kuttaris eventually...anyways the Burger King Cubone keychain is a childhood relic and everything else was purchased online. I'm also waiting for the Chandelure strap from the recent Sleepy Time Kuji to come in the mail.
