Sesame Street
(2009)
For Season 40, Zoe is smaller -- using the puppet that was used in the 2008 video special Abby in Wonderland, in which Zoe played the Dormouse. This version of Zoe has smaller eyes and a thinner head. Her hair is short and spiked up. Her arms are very thin. This puppet was only utilized for one season; afterwards, the previous puppet was reinstated.
Zoe-S49
Sesame Street
(2017-present)
As evidenced from behind the scenes photos taken during the taping of Season 49 in 2017, a few changes have been made to the Zoe puppet. The most prominent change is that she is unclothed again, returning to her pre-2002 appearance. She has more hair, which is less orange in color.
