Mombot is episode 21 of Season 2 of Sonic Boom, the CGI comedy series made by Technicolor Animation Productions with Sega of America. It premiered in the United States on 1 April 2017 on Boomerang.
Synopsis

Eggman’s Eggs-Boson Super-configurator can conjure a miniature black hole or give broccoli the flavour of applesauce, and it still loses the children’s science fair to Beth the Shrew’s model of the solar system. The judges rule him too tall to enter, and Beth wins a week as apprentice to the village’s leading scientist, who turns out to be Tails. Watching Lady Walrus dote on her son, Eggman realises what he’s missing and builds Mombot, a robot mother programmed to love him unconditionally.
At first it’s bliss, complete with a montage. Then she suggests he give up villainy for air-conditioner repair, arranges a peace-making movie date with Sonic, invites Sonic, Amy and Sticks to dinner, spots his Mantis Bot ambush without turning round and sends him to his room. Meanwhile Tails and Knuckles compete for Beth’s attention, science against smashing, until she wanders off with Sticks to learn about mind-control headphones.
Humiliated, Eggman plans to wipe Mombot’s memory with a magnet, but when the moment comes he can’t do it and sends her on a round-the-world cruise instead. As she hugs him, he turns to the camera and asks, “Does it always have to end on a joke?”
