Rock-a-Bye, Alpha 5

Alpha 5 has become incredibly sleepy lately, and he is starting to get run down from all these monster and Cog attacks. Worried over the Edenite prince's health, King Mondo capitalizes on the situation and orders Klank and Orbus to resurrect Somnibot. She is then tasked with infiltrating the Power Chamber and singing Alpha 5 to sleep, but the sleep-inducing robot falls in love with the prince first. The Rangers put Alpha into his room and tuck him in after teleporting into the Chamber and being informed of the attack by Zordon. Unfortunately, Somnibot's plan takes a devastating turn when Alpha turns ice-cold; his body temperature is dropping. Heaters are placed around Alpha's bed to keep him warm as he sleeps, however, and his body temperature is stabilized. Eventually, though, Alpha awakens from his beautiful dream world and is well-rested, much to the Rangers', Somnibot's, Delta 4's and Zordon's relief.

Delta 4 displays a lot of jealousy towards Somnibot throughout. King Mondo sends a transmission to the Power Chamber. Somnibot confirms that her mission is a success, but Alpha is to be kept warm as he sleeps peacefully.

Somnibot later defects to the Rangers' side after realizing that the Machine Empire is cruel towards its citizens - despite the Machine King and Queen worrying over Alpha's sleep deprivation at the beginning of the episode. However, the Rangers and Alpha firmly believe the Empire can change for the better.
