I wondered that today when flipping through channels and catching part of Wonder Pets! on Nick Jr. After asking Vogon if I was hallucinating, I paused my belief in reality and enjoyed the rest of the show, noticing its similarity to Go, Baby!, which I saw for the first time after
Bonus six degrees of trivia: Wonder Pets! and Piper O'Possum on Nick Jr, Go! Baby on Playhouse Disney, and Oobi on Noggin are all made by the same production company, Little Airplane. There's a demo reel on their site, but it starts out with Piper, which I tuned out and waited for the good stuff.
