Why Is Winnie the Pooh: Serious Detective Not Available on Amazon?

About Winnie the Pooh: Serious Detective, from BoardGameGeek:

We all remember and love the stories we discovered as kids - especially when they're just as rewarding to revisit as adults. And their original literary form isn't the only way to enjoy them. What if classic tales were reimagined as thrilling detective adventures? Winnie the Pooh: Serious Detective is a narrative-driven board game in which players take on the roles of beloved childhood characters - now turned detectives - to solve challenging and often peculiar mysteries. Inspired by the works of A. A. Milne, Lewis Carroll, and Arthurian legends, the game's three scenarios are rich with literary charm, layered storytelling, clever wordplay, and just the right touch of whimsy. You'll revisit the Hundred Acre Wood, Wonderland, and the court of Camelot - but not as you remember them. Something strange is afoot, and only a keen mind can uncover the truth. Each case was illustrated by a different artist in their unique style. The mysteries unfold across a beautifully illustrated map of interconnected location cards. Players use both shared and personal action dice to explore scenes, uncover clues, and reveal story cards - including testimonies, observations, puzzles, and more. Every discovery adds depth to the story and brings the group closer to cracking the case. Though designed with adults in mind, the game is also accessible and engaging for younger players - making it a perfect choice for a family game night with a touch of mystery. -description from the publisher
