It looks like a Volcano shape . I see tables of different colors . Perhaps they have to run to the Volcano structure..get a puzzle piece's , run back to the table . Look at Scout ..the poor thing is barely sprinting .
I give this challenge to Eliza , especially if it has anything to do with puzzles . Poor Chris last night , he totally missed that Tiki piece , he even went so far as to kick it out of his way at one point ..was anyone else yelling " Chris, you missed a piece ! It's under your feet ya big dummy " and I was dying because I knew that Jeffy knew and he could not point it out to Chris as that would have been unfair to the others .
