The Wondrous And Mysterious Tooth

My necklace is as mysterious and wondrous as a tiger shark.
It flies from the east wanting to be found.
As it is owned by me.
It's as colourful as a rainbow lorikeet.
Kwark!
It's as soft as a cushion and as cute as a butterfly,
Wooosh! Wooosh! Wooosh! Wooosh!
Whenever I wear it, I feel happiness inside,
It makes my heart full of crystals.
