The special features the regular human cast of Sesame Street along with several puppet characters, including Cookie Monster, Telly,[6] Bert[7] & Ernie,[8] The Count,[9] Grover,[10] and Oscar the Grouch.

Big Bird eventually finds Snuffy and they wander the Egyptian exhibit and encounter a ghost of an Egyptian prince named Sahu (Aram Chowdhury) and his cat who have been cursed to remain on Earth until he answers the question "Where does today meet yesterday?"

Big Bird considers all this too daunting and instead suggests Sahu remain on Earth and become "the only 4,000 year old kid on Sesame Street".

However, Snuffy thinks it is only fair they help Sahu be reunited with his parents, and Big Bird agrees they should work on the riddle.

When the demon appears that night, the question is answered correctly and Sahu is sent to Osiris (Fritz Weaver) to have his heart weighed.

Bob commends Cookie Monster for behaving himself inside the museum and rewards him by saying he can have anything for sale on a hot dog cart.

He encourages the viewers to visit their local museum, and comments on how staying perfectly still is tiring and wonders how statues can do it.

Bob holds Cookie Monster back and reminds him that he promised not to eat anything in the museum.

Then Cookie Monster breaks into song, with angelic choral accompaniment, about paintings, statues, and mummies, and how he understands how important it is to not devour them.
