Chief. Have you got any links to pictures of the toast that landed buttered side-down, and when the disappointed toast eater picked it up, there before him was a vision of the virgin Mary? Failing that have you got any links to amusingly shaped vegetables?
The Pacu is available in the Amazon and widely sold to Aquarists. Bet the owner was nipped and threw the thing away in disgust.
One fish I came across when in the Berbice area of Guyana was known locally as 'Crocodile'. The thing had spiky teeth and armoured scales and about 8" long. The locals wrapped it in an edible reed and boiled it - really tasted nice.
Picking the arnoured scales from the teeth was a task though. The dish was called 'Crocodile and sticks'.
