"It's Ziggy's birthday party and everyone's invited, especially Robbie Rotten. Stingy makes all kinds of excuses not to attend because he doesn't want to bring a gift."
Trivia
When Robbie reads the calendar, it is seen that Sportacus' birthday is on the 10th, like his actor Magnus Scheving (10 November). Ziggy's birthday is on the 14th, like his puppeteer Guðmundur Þór Kárason (14 June). Also, on the calendar, there is a photo of the original Stephanie (Julianna Rose Mauriello).
This episode was flimed from 9th to 12th May 2012.
This is the second time Ziggy's birthday is celebrated on the series, the first time being "Happy Brush Day."
While pretending not to notice Ziggy, Trixie asks Stephanie what she had for lunch. Stephanie answers "Chicken". So Stephanie doesn't only eat Sportscandy all the time.
Goofs
In the British dub, Trixie regains her American voice when she says "Now, Sportacus."
