Plug Boy became an internet sensation when he launched himself into a huge electrical socket in the ad about kids performing in a play.
But the Advertising Standards Authority (ASA) has received 35 complaints over the Christmas advert, with people scared children will copy the young lad by "playing with plug sockets".
The watchdog is currently looking into the complaints but a decision hasn't been made on whether or not to launch an investigation, The Mirror reports.
Fans of Plug Boy have now flooded the internet slamming the complainers as they accused them of "trying to ruin Christmas".
One said: "People are ridiculous. # PlugBoy is awesome and kids need to be brought up to distinguish between what's fiction and reality."
