The Golden Horseshoes (1) - S2-E6
Continuity mistake: As Sweet Stuff is talking to Surprise near the beginning of the episode, both of their legs are drawn far too short, making them look deformed.
Audio problem: When Fudgy McSwain and Rocky Ripple are at war, the First Tooth Baby Ponies escort the Newborn Twins to safety by taking them back to the Satin Slipper Sweet Shoppe. The sound of the twins crying starts before they move their heads with their mouths open and eyes closed.
Continuity mistake: At the beginning of the episode when Baby Fifi tries to feed Sniffles (pale purple newborn twin with pale pink hair), there is a close-up shot of her and Snookums (pale purple newborn twin with pale purple hair) in their high chair and the food in their bowls appears to be water. Sniffles throws her bowl onto Baby Fifi's head and the food turns brown. In the next close-up shot of the twins where they giggle, the food in Snookums' bowl has also changed brown.
Continuity mistake: During the song 'Babysitting,' Snookums has a pale pink body and medium pink hair as she bangs cymbals and Sniffles has a medium pink body and pale pink hair as she bangs a drum while Baby Fifi sings, "Babysitting, babysitting. Oh my aching head is splitting." Sniffles and Snookums then climb onto her back for a ride and for a split second, Snookums' hair and Sniffles's body both turn a darker shade of purple than at the beginning of the episode.
