Magic Kingdom’s Big Thunder Mountain Railroad reopened to parkgoers on May 3, 2026, following a massive 16-month refurbishment. While the coaster returned with smoother trackwork and a freshly painted Tumbleweed, eagle-eyed Disney fans noticed one glaring omission: the spinning possums that traditionally hung over the tracks were completely missing.

Now, just five months after the coaster welcomed back guests, Disney World is quietly making another update to the attraction. A mysterious new addition has appeared in the middle of Tumbleweed, signaling that a fan-favorite scene is finally on the verge of returning.
The Missing Piece of Tumbleweed
When mine trains splash through the flooded town of Tumbleweed, riders pass beneath a large, weathered tree. For decades, a thick branch extended out over the track, carrying a family of possums hanging upside down by their tails and spinning in circles as trains careened past.

However, when Big Thunder Mountain Railroad reopened in May, the branch was entirely gone, leaving only smooth, finished bark where it had connected. Disney quickly reassured fans that the missing critters remained part of the ride’s long-term design and would return “soon.” Yet, month after month passed with no sign of the spinning animals—until now.
Why the Possums Were Benched
The reason for the delay comes down to strict theme park safety protocols. Every attraction at Walt Disney World must maintain a strict “envelope of protection”—an invisible safety boundary around the ride vehicle that prevents guests from reaching out and making contact with scenery.

During the coaster’s 16-month overhaul, extensive track replacements and structural shifts altered the spatial alignment between the mine train and overhead elements. When Imagineering performed physical clearance tests before the May reopening, the original possum branch reportedly failed the safety test.
Rather than delaying the reopening of one of Magic Kingdom’s most popular rides, Disney opted to remove the branch and open it on schedule temporarily. At the same time, Imagineers engineered a solution behind the scenes.
What the New Tarp Means for Magic Kingdom
Fast forward to October 2026, and physical work has officially resumed inside Tumbleweed. Guests riding Big Thunder Mountain Railroad this week spotted a dark tarp wrapped around the section of the tree trunk where the possum branch had previously been attached.

Because the trunk was fully painted when the ride reopened in May, the sudden presence of a protective tarp suggests ongoing installation work. Imagineers have likely redesigned the branch to position the possums safely out of riders’ reach while keeping the classic visual joke intact.
While the animatronic possums themselves are not yet visible, the tarp is the clearest sign in five months that Imagineering is preparing to reinstall the branch.

What’s Next for Frontierland?
For Disney Parks fans, seeing Imagineers invest time and effort in re-engineering a minor scene element demonstrates dedication to detail. With the tarp now in place, returning guests should keep a close eye on Tumbleweed during their next trip, as the spinning possums could make their official comeback to Big Thunder Mountain Railroad at any moment.
