It’s jumping truck

“Mommy , mommy, a jumping truck”, my son yelled.
“Yeah.that’s a truck”, I said.
“No, a jumping truck”, he corrected me.
“It’s a U Haul…see U-H-A-U-L” , I promptly corrected him and stood very Mommyish.
“See a frog… a green frog.
It’s a jumping truck. ” , he proclaimed.
Seeing the big green frog painted on the truck’s body, I finally ‘got it’.
Both of us shouted , ” Daddy, a jumping truck.”
