Snake in the Grass (also known as All Mixed Up) is a recurring challenge in Survivor that originated in Survivor: Philippines.


Castaways must go over and under a series of hurdles to retrieve bags of puzzle pieces. The first three to finish will move on to the final round, where they have to use the puzzle pieces to solve a puzzle in the shape of a snake. The first contestant to finish their snake puzzle wins.

In the tribal version of this challenge, a number combination lock was added to the course prior to the snake puzzle.


The challenge debuted in Philippines as the final ten Immunity Challenge where the first three castaways to collect their bags and cross the finish line would move on to the final round. There, Jeff Kent and Pete Yurkowski pulled out ahead, as Jonathan Penner struggled solving his snake puzzle. However, Jonathan managed to catch up and finish his puzzle just ahead of Jeff to win a crucial immunity.

In David vs. Goliath, the challenge reappeared as a post-merge Reward Challenge where each team would have to grab a bag hanging from an a-frame and solve a number combination lock before solving their snake puzzle. As there were only five members on each team, Carl Boudreaux was left out in a random draw and had no shot at reward. The orange team of Alec Merlino, Dan Rengering, Davie Rickenbacker, Kara Kay, and Mike White took the lead on the obstacle course and held on to it to solve their puzzle first and win reward.
