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.
