The Unique Friendship of Grover and Steve

On the Great Plains, we find Grover, a donkey and Steve, an ostrich, who are the best of friends despite their differences.
The other animals on the plains just cannot understand how they are even friends. Donkeys and ostriches are just too different!
For Grover and Steve, while there are many differences between the two, what's most important to them is the bond of friendship.
