LEGO Disney 43301 Toy Story Slinky Dog Book Nook Rumoured For April 2026

As the official trailer for Toy Story 5 dropped just yesterday, the LEGO Group are expected to be one of many toy companies producing merchandise ahead of the fifth and possibly final Toy Story film. In particular, the LEGO Disney theme will be releasing a brand new 18+ model with 43301 Toy Story Slinky Dog Book Nook. Releasing on the 1st of April 2026, 43301 includes a total of 1,311 pieces retailing for $149.99 / €149.99 / £129.99.

Our second LEGO Disney adult-oriented set, following on from next month's 43300 Winnie The Pooh, returns to the LEGO Book Nook subtheme, which first began last summer with the release of 10351 Sherlock Holmes: Book Nook and 10367 The Lord of the Rings: Balrog Book Nook. This time, however, rather than an iconic location or battle scene, we're getting a large brick-built version of Slinky Dog to be placed between books on a shelf.

Even though current rumours suggest that the set is a Book Nook, 43301 will more likely be built as a functional bookend that can be placed at the end of a row of books to keep them upright, similar to September 2025's 75691 Glinda & Elphaba Bookends. Given Slinky's unique flexible spring design, it's highly likely the set will be split into two halves - his front and back - with his spring body 'stretching' across your book collection.

The front end will feature Slinky's head, front paws and a portion of this spring. A brick-built, detailed face belonging to the loveable toy will appear with a highly expressive facial expression, portraying the character perfectly. The rest of Slinky's spring is found at the back of the bookend/book nook, along with his hindquarters and wagging tail. The sections can either be connected to create more of a book nook structure or placed at either end of a bookshelf, creating an optical illusion that Slinky's body is stretching through the books.

The base that the brick-built Slinky Dog is placed on is another talking point of the build. With the set replicating a book nook of a large brick-built character, the base won't be the focal point of 43301, but may still include various brick-built details and Easter eggs. For example, we may see references to Andy's Room or oversized alphabet blocks and board game pieces to establish a brick-built toy scale.

What has been confirmed, however, is that two LEGO Minifigures will be included in 43301 Toy Story Slinky Dog Book Nook. These are Woody, who will likely be the exact same as his most recent appearance in 40774 Classic Animation Scenes GWP and our first ever Minifigure scale version of Slinky Dog. The reliable leaker Unibricks on Instagram reports that Slinky will be made from two pieces with a rubber middle representing the spring.
