Here's a book recommendation direct from my son:
Jon Agee's Mr. Putney’s Quacking Dog
“I like it because of the very funny jokes.”
Agee really appeals to my boy because
of the word play. Like many of Agee's books,
Putney dispenses with conventional
narrative to better indulge in
outrageous word related silliness.
Putney lives with a wacky menagerie
of animals who often make
themselves useful in punny ways.
Each morning, Putney's alarmodillo wakes
him for another day playing with his
anteloop and taking care of his poor
ill hippospotamus.
My ten year old loves this book and
would have loved it any time these past
five years. I worried a little lest he fasten
on the jokes too strongly (as boys with or
without autism sometimes do) but he
contents himself with occasionally
saying "Alarmodillo. Do you get it?"
or the like remark.
This imaginary world works well for
kids who enjoy word based silliness
with a solid structure visible beneath
the nonsense.
