What toy story pins are released during special park events?

The query asks about Toy Story pins released during special park events, but the available evidence does not contain any information about Toy Story merchandise, collectible pins, or Disney park event releases. The primary evidence provided is about The Rocketeer film (1991), which is unrelated to Toy Story or Disney park merchandise. Without specific evidence about Toy Story pins or park event merchandise, I cannot provide accurate information about this topic. My response is limited to the verified evidence provided, and I cannot rely on general knowledge beyond what is explicitly stated in the sources.
