WARNING! This article contains spoilers for The Boss Baby: Back in Business Season Three!
Happy Sedengry is a "babblist" who claims to understand baby speech. He was hired by Marsha Krinkle to give a guest presentation at the play group Theodore "the Boss Baby" Templeton joined after he was fired from his job at Baby Corp, where he pretended to understand what the babies were saying in front of their parents. The Boss Baby and his fellow babies set out to prove Happy Sedengry was a liar before their parents got scammed. Happy was later revealed to be the C.E.O. of Bubeezee.In the last episode, he was blackmailing Boss Baby saying that he will show the video of the talking baby if he doesn't work for Bubeezee. Happy got arrested at the end of the last episode.
Weirdly, he seems to not care about Baby Corp,and is not fazed upon the discovery that babies can talk.
