Stuck on Kolepom Island

Over your Christmas vacation, you decided to go on an expedition to Kolepom Island because you heard there was a sighting of Attenborough's echidna there! Unfortunately, soon after you arrived at the village to meet your guide, the chief of the tribe took your weapons and locked you in a hut.

It seems the chief will not deal with any Westerners unless they prove that they respect the tribe's culture. He has given you the problem below to prove your worth. If you can solve it before the sun sets, he will be your personal guide to find Attenborough's echidna which he claims to have seen with his own eyes. But if you fail, you will be cooked and eaten at their annual feast of the echidna in three days time.

Good luck!
