Wainscott Studios is the only studio to use Shadowmation, a technique created by Mitchell Kriegman, to bring the puppets to life by combining live-action animatronic characters with computer generated animation in real time, high definition virtual environments powered by video game engines.

Additional puppetry was provided by Patrick Holmes, Carol Binion, Frankie Cordiro, Eric Engelhardt, Jim Kroupa, Paul McGinnis, John Kennedy, Jodi Eichelberger, Heather Asch, Amanda Maddock, David Jordan, and Lara MacLean.

Many of the puppeteers come from similar shows, primarily Bear in the Big Blue House, Jellybean Jungle, and The Book of Pooh, another show involving Shadowmation, a technique that combines live-action, bunraku-style puppetry, and computer-generated animation.

At the end of all episodes, Snook sings the closing song, "Try to Touch the Sky", although this is often followed by short segments in which Snook ends an exploring or scientific activity and gives some fun facts about the various species of animals that live in the World Tree.

The show was added to Amazon Prime Video on August 12, 2022 after PBS Kids acquired the streaming rights on July 27, 2022, officially marking the program's return to PBS Kids in any platform after 12 years.
