Ugh, can't believe I'm posting this question. Wagon Jr. is on day 3 of fever so it's been Bubble Guppies world in our house. I think my two favorites are the Supermarket song and Trucks are Tough. We only watch season 1 free on Amazon Prime, but we did buy one episode of season 3, the School one. I like the song but Wagon Jr. is afraid of the robot in the episode.. So we stopped watching it. Bye bye $2.99.
