Here's a special exclusive for 2016!
At the SanDiego Comic Con, Sanrio & Sega announced that Sonic would do a partnership with Hello Kitty to make this year's exclusive toy. It's a Hello Kitty plush that's dressed up in a cute little Super Sonic suit. Hello has dressed up as Sonic before (but that's a Japan Plush) as regular Sonic. Notice the turned up spikes & classic shoes.

She keeps her red bow, but even her ears have the gold border. To make it extra special, they chose a gold fabric that's actually smooth and shiny/metallic.
It's a bit of an unusual exclusive...because it's a Sonic themed item, rather than a directly Sonic item. Notice the cloth side tag has the collaberation logos on it as well. Over all, it looks quality (they actually changed the spikes, it's not just a re-color re-release) with fun shiny fabric & good detail. This was limited to 1000 pieces and cost $40 while only being sold there.

Gold shiny fabric like this can sometimes suffer from "Gold Fabric Age Dulling", as can similarly shiny silver fabric. Humidity /air condition may play a part in how the fabric retains the shine as it ages. Wear also affects it. If it's moved/twisted/wrinkled repeatedly, it can lose shine. It's important to keep this plush quite safe and in a dry controlled environment.
