What makes certain toy story items disney exclusive?

The question asks about Disney exclusive Toy Story items, but the verified evidence provided focuses exclusively on Disney's Animated Storybook video game series from the mid-to-late 1990s. This evidence establishes that Disney Interactive published point-and-click adventure games based on both Walt Disney Feature Animation and Pixar films, developed primarily by Media Station for children ages four to eight. While this shows Disney had publishing rights for interactive content based on Pixar properties including Toy Story, the evidence does not address toy merchandise, exclusivity arrangements, or specific licensing deals that would explain why certain Toy Story items are branded as Disney exclusive. The source material appears incomplete for answering the specific query about toy exclusivity.
