Ostrich
That ostrich there takes fatherly care
He stays with his egg clutch for days (50!)
If twenty babies hatch and, "Need seeds!"
He's happy to help with that phase
Rhino
I've got a two-ton pal who runs with a crash
She charges credit when she's rationing cash
Her horn is made of keratin
Her skin is latticed collagen
And tapirs are her next of kin
Rhinoceros, rhinoceros
Go rhino, go!
