Baby Beel has been crying all night for the past three nights, which is causing Tatsumi and the whole neighbourhood to get very little sleep. Wanting to stop his night crying to avoid being chased out of their house, the Tatsumi family attempt to play with Baby Beel all day in order to tire him out come nighttime. Despite managing to get him to sleep, Baby Beel still wakes up and cries in the middle of the night. After Tatsumi spends the day dealing with a sleep deprived TKKH, Hilda brings a toy that calms Baby Beel down, but is even noisier than his crying.
