That octopus...

That octopus, I'm sure,
Is a Spanish spy,
Or someone used some lure,
And that made it bite
The oyster in the wrong box.
German fans have run amuck
As it was a real shock.
No doubt it's bad luck.
But two years ago it mocked
While predicting Spain would lose,
The whole Germany is rocked.
Find a better beast to use.
