Kieren is sad because his job is very stressful and his boss is being mean. His job involves knowing lots of species of birds and it’s really hard when they all look alike.

The giraffe got green by gulping gel. It will go with the great gnu geologist and play a game of gobble the grapefruit. The gnu is very good at the game but the giraffe has more to gain.
