A new Happy Meal mascot introduced by
Happy, as the new mascot is named, is an animated red box with a pair of bulging eyes and a mouthful of large teeth.
In a tweet by McDonald's on Monday, the company introduced Happy as "our newest friend."
But some Twitter users weren't so friendly, responding with gems such as: "I didn't want to sleep tonight." Another user wrote: "That is not right with God."
At the other end of the spectrum, a writer criticized what he characterized as an underwhelming mascot: "Someone stuck a mouth on the box. How many years was this in development?"
In a statement, a McDonald's spokeswoman said "social media is a great place to have a conversation and express an opinion, but not all comments reflect the broader view."
