Philbert is was also featured in several other episode of the show, including "How Did My Dog Do That?" where he helps Sid learn about the different skeletal systems.
Like all of the characters in Sid the Science Kid, Philbert was brought to life using the groundbreaking Henson Digital Performance Studio.

The two images were then simultaneously composited together to create a single integrated character.
