While the lion roars

I like to swish and swash through the jungle, swinging on vines with my favourite monkeys while the lion roars.
I like to watch the speedy cheetah dashing past the trees, chasing a herd of buffalos while the lion roars.
I like to hear the snake slithering past the river bank, following its prey while the lion roars.
The monkeys swing, the cheetah dashes, the snake slithers but I can't hear the lion roaring. The roaring lion is sleeping.
