Babble

Babbles are a fictional species seen in the 2002 animated film The King's Beard.

Description
Babbles are magical creatures about fourty centimeters long, shaped like a wide pillow, with turquoise fur and bulging yellow eyes. They have a compulsion to repeat anything said in its vicinity, which makes them useful for dictations, but annoying for pretty much any other purpose. Although they are unable to talk for themselves, Babbles are sapient creatures, and can be granted the ability to talk by a fairy.
