Russian Doll Spy Whales

The Russians originally
Had heard of spy whales
From one of their agents/spies
Based in North Wales, UK
And due to a simple typo
And general misunderstanding
The KGB, assumed that the British Government
Were training Welsh people to become spies
The British Government got wind of this
And deliberately gave their spy whales names
Such as Evan, Hugh, and Taff
Thus further confusing the KGB
But the error was later realised
Thence the Russians began building robotic whales
But they kept going rusty
Next they tried genetic engineering whales
By placing a Great White Shark within the Whale
Then a Dolphin within the Great White
Within the Dolphin, was a Porpoise
And inside the Porpoise, was a Tuna
Inside the Tuna, was a Red Herring
And inside all of these, was a type of killer Sprat!
