What are the different toy story plush sizes available?

Based on the verified evidence supplied, there is no mention of any specific Toy Story plush sizes. The knowledge graph identifies the Toy Story franchise, and the Wikipedia entry lists characters from that franchise, but neither source includes details about merchandise dimensions or available sizes. Consequently, we cannot provide a list of plush sizes for Toy Story characters. If you need accurate information on plush size options, you would need to consult official Toy Story merchandise listings, retailer product pages, or the official Disney/Pixar toy partner announcements.
