I'm sorry for being late guys, just after being hacked and all...
So for this challenge, you will have to hide, and find your way back to the dock to win invincibility, the first 3 people to make it back WILL ALL WIN INVINCIBILITY.
You must post *hides in (any place)*, then 3 times *runs back to dock* and then *wins immunity*. These must be at least 30 mins apart.
