We consider every day a plus
To spend it with a platypus
We're always so ecstatic
'Cause he's semi aquatic
Our Ornithorhynchus anatinus
Brings smiles to the both of us
Life's never fuddie duddy
With our webfooted buddy

When we're brushing our teeth, (oooh) It's better
Tying our shoes, (oh, yeah) It's better
Combing our hair, It's better
Like we're a cheese sandwich and he's the cheddar
Blinking our eyes, (oh, yeah) It's better
Breathing in and out, It's better (So much better)
Sitting in a chair, It's better
And taking a bath, just a little bit wetter

Every day is such a dream
When you start it with a monotreme
He's duckbilled and
he's beaver tailed and hairy (You know that he's hairy)

Everything's better with Perry
(Everything's better with Perry)
Everything's better with Perry
(Everything's better with Perry)
Everything is better with Perry
(Everything is better, everything is better with Perry)
Everything's better and we
Just want to tell you Perry
Everything's better with you (Better with you)
