Ok, so I found this album with Phuket pics of a family.Album by a Family
Elephants walking over you while you are laying down = part of the elephant show.Supporting image
From the Phuket Zoo
Our staff will take a Polaroid snap of you posing with our Tigers. You can choose a young tiger or a fully-grown male to sit with depending on your courage! The family poses with the tiger here
Anyways, what I'm trying to say is these make it seem like the Elephant Walk-Over and Tiger Photo-Op are the two detour options.
One last thing: the chimpanzee is not part of the Monkey show, because according from the Phuket Zoo
We use short-tailed macaque monkeys for this show. They are still a kind of common wild animal in Thailand.
So going back to the family album above, they have a picture with a chimpanzee here
, but that's a male one (you can see it's scrotum, and the penis can be seen in the next photo
). However, the one in the recent preview is a female.
So I'm just gonna guess that teams have to find the cage (
) of the female chimp because that's where the clue box for the detour is, or she might be the one giving the clue...
(sorry, I think that second possible scenario is exploitation).
