Words: wacky, wad, waddle, wade

I went to the zoo,
For somethin' to do,
And low 'n behold,
'Twas a penguin exhibit,
That stopped me cold.

I watched goofy birds waddle, around,
All over their pen, as if struttin' downtown.

Webbed feet 'n a tuxedo, wacky as heck,
Movin' slower than if a wad of mud,
Had stiffened their neck.

I watched 'em wade through,
The habitat and all,
Like a toddler's first winter,
And the repeated fall.
