I'm so glad you made it
we'll continue the quest
I'm straining my wit
to develop this test

First we'll need an adorable child,
Floppity loppity and fuzz scrubbers in pairs.
Next a cheerful leap dance might be something wild,
an expression of very few weighty cares.
A gecko climbing upside down and across walls,
what is the force that prevents nasty falls?
An amazing number you'll find throughout nature and design
guides glittering proportion and aids a pleasing line.

Take the first four digits with dot included,
and end the five words with what you've concluded.
At the home of music in the sky,
you're 'tada_got_it' as past the waveforms you'll fly.
