Trivia

• The opening backyard scenes in this season are considerably longer than in the following seasons.

• This is the only season where Pablo is voiced by Zach Tyler Eisen.
• This is also the only season where Tyrone's singing voice is provided by Corwin C. Tuggles.
• This season is available on Nickelodeon's video-on-demand service. It was the first season to surface on these platforms.
