The Flying Narwhal, not unlike the flying Rhino occurs when one dons a construction helmet with a long spiral dildo. Then whilst swimming have the receiver float on their back or floatation device and the Narwhal swim ferociously toward them and jump or dash quickly into their twat or anus, spearing them harpoon-like
As i peered through my poolside window, i saw him tanning on a floatsie in the pool. The narwhal spotted him too, before i could shout a warning, swam across and took a flying leap directly into his anus thus puncturing him with a flying narwhal.

A song about Narwhals.
Very, odd.
narwhal song:

narwhals, narwhasl, swimming in the ocean
causing a commotion
coz they are so awesome
narhwals, swimming in the ocean, very big and very white they beat a polar bear in a fight
like an underwater unicorn, they've got kick ass facial horn, they're the jedi of the sea
