For my sisters birthday party she had a survivor party. We decided that 3 on each of the two tribes would be a good amount, so she invited 5 of her friends. For the names of the tribes we googled names of survivor tribes from the show and she picked her two favorite ones,Dabu and Airai. We then picked the tribe colours, Dabu was pink and Airai was green. So we decorated one room which we decided that would be our tribal council, one side was fully green with green streamers down the wall, green streamers comeing from the wall to the light, green balloons covering that half of the room and their tribe banner hanging on the wall. So Dabus side was the same but all in pink. We didnt really bother with decorating the room you went to to vote people out so we just put a desk, a chair, a jar that you could not see into and a video camera in front of it so it wa just like on the real survivor when they say who they are voting for. As soon as all the girls got there we opened presents so we could get straight onto survivor. The first challenge was an all on all imunity idol challenge, our imunity idol that was up for grabs was a pair of fairy wings. The challenge was who could stand on one leg the longest. So everyone found a space and we started the stopwatch, the only rules of this challenge were, no touching anything, stay on the same leg you started on. Last one standing one the fairy wings for this round. The next challenge was a tribe on tribe challenge , tug o war. It was best of three, each time you swapped ends. The loosing tribe was up for elimination at tribal council. The winning tribe won a chocolate bar each. Everyone voted in tribal council, the person with the  imunity idol could not be voted out. So it was 5 left now.  The imunity idol challenge was an obstacle course, individual. First they had to spin around in circles 10 times, then walk 'the plank' (a piece of wood about 5m long on concrete  blocks) if they fell off they had to start again, after the plank the had to eat 1 whole dry weetbix then solve a puzzle. The quickest time won. Then it was the tribe on tribe challenge. Each tribe had a tub full of ice and 35 marbles. One at a time the girls had to get as many marbles out using only their toes in 1 minute. Each girls amount was added together and the highest total won and got choc. bar each. Then it was tribal council for the loosing tribe. Now there were 4 left.There was only 1 person left on one tribe and 3 on the other so it went individual not tribes from now on, but the person who won tribe they were on all got a choc. bar each. Next was an imunity idol challenge, it was called what food is it. one at a time we took them into a room blindfolded, we gave them different foods and they had to guess what they were,we took their first guess,there was gummybears in jelly, pattee, some type of cheese and peeled grapes covered in salt. The person who guessed the most correct won and advantage in the next challenge. the next challenge, there were small hoops hanging from string, the girls had to stand 5m back behind their hoop (the girl with advantage stood 4m back)they had to throw 3 ping pong balls through, when they did that they had to solve a puzzle, first done won a choc.bar. Then it was tribal council and another girl was voted out to the dury. There was 3 left now. The next challenge was 4 the advantage in the next. There was a puzzle up the right way, the girls had to get on their heads(handstand,headstand) and solve the puzzle, when they thought they had the answer they had to run upstairs and tell me, if correct they won, if incorrect they had to go back down and keep going. The next challenge there were paper cup pyramids set up, each girl was 5m back and had to use a sling shot to shoot down the cups 5 times, first done won. The person with the advantage had some one who threw their things they used to shoot down the cups as there were only 2 each, everyone else had to go and get theirs themselfs, taking lots of time if they missed. The winner won a choc.bar. Then it was tribal council, another girl was voted out so there was only 1 left now.  There was no challenge in this round, just a big tribal council where members of the dury asked them questions, then the two left left the room and the dury voted on the winner. They came back in and the winner was announced, she won a cute clutch handbag with stuff inside. Later on we watched the the girls voting people off from the video camera, it was funny haha. The rest of the night it was a normal sleepover, we lite their survivor torches and took photos, we had pizza for dinner and just watched movies and ate LOTS of lollies.  For costumes we told the girls their tribe colour the day before so they could dress up in that colour. Party snacks was just the noraml party food, lollies, chips etc. This was such a cool party and the girls LOVED it !! I would definetly recommend it for your next birthday party !!
