Grumpy Monkey Up All Night! by the Langs - 4 stars

[Theresa]

Jim Panzee has been invited to a sleepover at his family's home, and Norman invites himself along to experience the 'all night' festivities. The list of entertainments was funny, the drawings first rate. My favorite moment was the family portrait Jim showed Norman when excitedly telling him about the sleepover invite. All were grump-faced except his little brother Tim.
