北极熊克努特 Knut Having a Shitty Day

Knut, he is a teddy bear,
but he has no mama now,
still he is sassy and happy,
and the star of the zoo!

Little critter all in white,
and he got all cuddly soft,
everyone loves Knut so much,
we're so glad you're here!

Knut, Knut,
little polar bear from the zoo,
Knut, Knut,
life is good for you.
