"Prunella the Packrat"
To attend a cooking class run by famous chef Francois Puffeau, Muffy has to carpool with Buster and Arthur after the Crosswire limousine breaks down. Buster wants this to be the best car pool ever, but his rolling party on wheels turns into a disaster. Can the kids stop fighting long enough to see the sights right in front of them?
The episode begins with Muffy in her limo about to go to her cooking class, but the limo is broken. So she has to ride in Buster's mom's car with Arthur and Buster. The first ride did not go well, because the CD player is broken. At cooking class, Chef Puffeau suggests berries for the fruit pastry and congratulates Buster for letting nature do the cooking. The second ride flopped too, because there was no right turn, the right ramp was closed, and the food was ruined. At cooking class, Chef Puffeau liked the berries, but said they are covered in egg and orders him, Buster, and Muffy to peel the onions. The final ride was worse. While Arthur, Buster, and Muffy were playing car bingo, they got a flat tire. Bitzi is fixing it, which inspired Muffy to rename her show "Muffy Crosswire: Master Mechanic." Arthur got a tangerine torte for Dad and peaches for everybody and they keep carpooling, finishing the episode.
- The song on the radio is also heard on Poor Muffy.
- In all scenes inside the car, the window cranks disappeared.
- In broadcast order, this is the last episode to be produced by Cookie Jar Entertainment before moving to 9 Story Entertainment, the last episode to use digital ink and paint, the last episode to feature a title card that was used during the first 15 seasons of the show in the US, Dallas Jokic's last episode as the voice of Arthur and the last episode with the characters having red tongues before it switched to white tongues just like season 1.
