Isabel is a call bell (duh!) who has eyes, these eyes are always fixed and stare right through you. She is a permanent resident of The Furchester Hotel, so whenever you stay there, your greeted by a bell that will never keep her eyes off you. She is the stuff of nightmares for many, especially when she gets Using Too Much Sauce, where her eyes bulge out and her fur comes off, and believe it or not, this abomination is also a muppet! Why else would it be in a hotel filled with them? She is even part of the Elmo Gang.
Her only shame appearance is as a playable character in Grand Theft Sesame Street: The Furchester Hotel, but she does nothing but sit there.
