Peter's been invited to go on a safari. He's brought:
1. Uncle Nigel, who's an explorer
2. hiking shorts
3. a canteen
But what he will need most is a bit of gumption.
(
Gumption: n. Courage; spunk; fortitude; resourcefulness; good sense.)
Oh, wait...there are crocodiles in the river? Then he might need a lot of it!
