Kind of a prequel to 'Little lost pony', but can be read seperately.

Out in the meadow,

Out by the lake,

Where everything's quiet,

And nothing's awake,

Is a little lost pony,

Innocent and sweet,

With seaweed in her mane,

And water pooled at her feet.

She waits by the loch,

Waiting for a snack,

For a silly little child

To climb on her back.

Standing by the loch,

Under the moon,

She waits for her prey,

Hopes it'll come soon.

Out in the meadow,

Beside the lake,

Stands the pony,

While nothing else is awake,

Little lost pony,

She looks innocent and sweet,

But she's really a kelpie,

After something - somebody - to eat.
