Glee-Go is a character that appeared in the 2021 cartoon show episode "Alien Smurf". He is an alien that originally appeared as a ball of light that assumed the form of a Smurf in order to make friends with the lifeforms he was visiting. However, as most Smurfs mistook him for Jokey (the form that he had assumed), Glee-Go used his remote-control device to hypnotize the Smurfs into being his friends. The only Smurf he didn't hypnotize was Smurfette since she was a girl, and he believed girls have cooties. Smurfette brought Storm, Blossom, and Lily to help put an end to Glee-Go's control over the Smurfs. Eventually, Glee-Go's parents (who were also balls of light) showed up, admonished Glee-Go for his behavior before restoring the Smurfs to their senses and ask Glee-Go to apologize to the girls for being rude to them as he does before reverting back into being a ball of light, and the three aliens vanish.
His character was voiced by an uncredited Madeleine Fletcher.
