As of Monday afternoon, the most recent post on Elmo's X account featured a picture of the red, fuzzy muppet with his newly-adopted puppy, Tango. "Happy Gotcha Day Tango! Elmo is so lucky to have a furry friend like you!" Elmo's account on X is now "secured," according to a Sesame Workshop spokesperson.

The account of the 3-year-old Sesame Street character turned hateful and certainly not suitable for kids. Here's what the hacked account said.

The X account belonging to the beloved "Sesame Street" character was hacked Sunday night and posted a series of antisemitic messages.
