The crocodile heart.

Hungry, m-angry, Croco Crook looked for food, for treats and stout.
Heart he saw so heart he bit,
Now ts too late, his lifeend's fire was lit,
No clue had he about the heart he bit,

T' belonged to a miss called Croco Brook,
the most beauti Croc in lake Manook,
Now she's dead, her heart's a drift,
lost between Crook's sharp, firm teeth.
