Nungwi, Tanzania
Whilst eating breakfast we noticed 3 travellers that are staying in the same place. They had been sat around for a while, 2 men and a woman. The men went off swimming but came back only 10 minutes later and one of them was hopping and only able to walk if half carried by his friend!
As he got closer we could see that his ankle was really swollen and red and looked very painful, he had trodden on a sea urchin! Ouch!!! We're going snorkelling this afternoon ...
