Larger still, is this 15 inch classic style Jazwares Sonic plush. He's their biggest yet, and seems well constructed. Notice the 'thumbs up' and 1 pointing finger hand pose. Should be between $18 and $24.99 at Toys R Us. He is sold inside a small cardboard 'chair' like open top item. He's strapped in there to be sort of 'sitting'. 

Here's the out of box fan photos for this big plush. As you can see, if you want a cute style plush, this is a good one to have. The fabric is really soft, and he's solidly stuffed. However, he can have stitch/ripping issues around the spikes (near head) and backs of the heels. His expression is nice, but the ears seem a little off...look how the one in the store photo above is oddly sewn on. He also has a problem at the top of his legs where they meet the body (disguised by the angle in JW stock photo above) as you can see they slim down to nothing where they meet the body. His spikes are good, well formed and seem in proportion. The hands look like they do in the original photo, though are a tad small. Over all though, he seems a good, solid quality and cute plush.
