Real-life Monsters of Babblarna

Babblarna is known for cute characters to educate and entertain toddler via cartoons, games and toys.

The saga says, they can only leave a household, until the haunted toddler repeats their gibberish babble at least once.

My 8-mo daughter's favorite toys & cartoon, Babblarna (The Babblers) are Swedish fictional characters used as children's language tools, created by illustrator and writer Annelie Tisell. The characters are inspired by professor Irene Johansson and the Karlstadmodel to train people with vocal, language and communication problems
