100 word challenge

It was a hot and humid day in the rainforest and the tribe were hunting for animals to eat for dinner. As Umbungo aimed his blowpipe up into the trees at a monkey, he felt something crawling up his leg.
"Keep still Umbungo," said ZamZam.
"There is a giant ant on your leg!" 
Umbungo was terrified of ants: he was bitten by one as child. 
"Get it off me ZamZam!" cried Umbungo. 
So ZamZam pulled out his dagger and hit the ant as hard as he could, but without realising he had actually amputated Umbungo's leg! 
Umbungo's face turned a deeper shade of red, he really wasn't happy!
