Mama Wagtail was worried. Baby Grumpus just did not know how to show that he was happy.
“Turn up the corners of your mouth just a wee bit, Grumpus,” Mama Wagtail would say.
But little Grumpus only looked grumpier.
“I cannot,” he said, ruffling his feathers.
“My mouth goes down instead of up.”
Mama Wagtail had an idea. She took Grumpus and flew down to Dog.
“Dog, how do you show that you are happy?” she asked.
“Woof!” barked Dog. “I wag my tail really hard when I am happy.”
Mama Wagtail then went to Cat.
“Cat, how do you show that you are happy?” she asked.
“Miaow!” mewed Cat. “I purr when I feel happy.”
