Good Night, Tucked in Tight is a Sesame Street book in the "Happy, Healthy Monsters" series.

Grover and Elmo teach readers about getting a good night's sleep. In the guise of the "Sleepytime Monster", Grover appears in Elmo's dream, and the two then "visit" all over Sesame Street, hoping to sprinkle Sleepy Dust to help their friends fall asleep. But, alas, no one is ready for bed. Meanwhile, Grover dispenses Sleep Facts and Tips, gently telling readers why it's important to get enough sleep and how to make bedtime easy and pleasant.
