The Grinch is a Dr. Seuss' character featured in the book How the Grinch Stole Christmas!
The grumpy, anti-holiday spirit of the character has led to the term "Grinch" coming to refer a person opposed to Christmas time celebrations.
He first debuted as a Falloon debuted in 1997 as the Holiday Ambassador, and he returned again in 2002 to promote the Macy's Holiday Parade, where he also appeared that same year.
In 2017, after a 15 year hiatus The Grinch will return as a traditional character balloon, featuring himself and Max. This balloon will be based on his appearance in Illumination Entertainment's film adaptation of How the Grinch Stole Christmas!.
